Answer: An electric circuit can be defined as a closed path through which electric current can flow. Various components such as battery, resistor, wire, key, bulb etc. can be connected in different ways to construct an electric circuit.
What is a circuit simple definition for kids?
A circuit is a path for electricity to move through. It's sort of like a big loop. As electricity moves, or flows, the electricity might light a bulb, turn a fan, or make your toaster get hot.
What is short circuit grade 7?
Short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit. This results in excessive current flow in the power source through the 'short,' and may even cause the power source to be destroyed.

Simple circuit:
A circuit consisting of simple electrical elements like cell, key, bulb and connecting wires is called a simple circuit. Simple circuit. The above circuit is simple because it has simple electrical elements like a battery, bulb and switch.
How do you write a simple circuit?
Series and Parallel Electrical Circuits
Electric circuits can be set up in two ways: In a Series Circuit or a Parallel Circuit. In a Series Circuit, all of the electrical current flows through each part of the circuit. In a Parallel Circuit, the current is divided into separate paths.

Short-circuit develops when live wire comes into contact with neutral wire. 1. Overloading occurs when the amount of current drawn by the source exceeds the amount of current the source can supply. 2. The current flow is high at the time of short-circuit.
How do you make a class 7 circuit?
A flow of large amount of current in a circuit, beyond the permissible value of current, is called overloading. It occurs when many electrical appliances of high power rating, such as a geyser, a heater, an oven, a motor, etc., are switched on simultaneously. This causes fire.
What are the 4 parts of a simple circuit?
Short-circuiting of a circuit is defined as an abnormal connection between two nodes of an electric circuit intended to be at different voltages. If the insulation on the wire or cable used in the wiring breaks, then live wire comes in contact with the neutral wire, resulting in a short circuit.
What is short circuit and overloading Class 7?
Short circuiting happens when live wire and neutral wires of domestic circuit come in contact accidently. As a result of short circuit, the resistance of the circuit decreases to very small value and current increases enormously. It results in heating up fuse wire and breaking up circuit. it may also cause fire.
What is overloading Class 7?

What is a series circuit? In a series circuit, which is also known as a series connection, the circuit elements are arranged in a single path. This means that, if there are three resistors in series, the same current must flow through all 3. In a series circuit, the current is the same in all three resistors.
What is a circuit Grade 10?
An electric circuit has to have a power source, wires for the electricity to flow through, and a device such as a lamp or a motor that uses the electric current.

How do circuits work for kids?
Electric circuits
An electric circuit has three parts: An energy source – like a battery or mains power. An energy receiver – like a lightbulb. An energy pathway – like a wire.
What is a parallel circuit Grade 7?
A source, i.e., power; a path for the electrons to flow, it could be made of conductive wire or printed on a circuit board; and components or devices that the current will flow through; and a return, i.e, a ground. Those are the three things all electronics circuits require.
What is circuit class 12?
They happen when a high-volume electrical current is passed through a low-resistance path that isn't meant to carry electricity. Short circuits occur when a live wire makes contact with a conductive object that it should not have. A short circuit can damage appliances, cause electrical shock, or even start a fire.
What is closed circuit class 7?
An overloaded circuit is an electric circuit that is carrying more current than it is designed to handle, creating a danger of fire through overheating. Overloading happens when too many appliances which work on high power are connected through the same socket. This will draw a very large current from the circuit.
What are 3 main parts of circuit?
Flexi Says: A short circuit in an electric fuse happens when the current bypasses the main circuit and takes a shorter path with less resistance. This can occur due to faulty wiring or a breakdown in insulation.
What are the 3 types of circuits?
The short circuit occurs in the system when the neutral and the live wire comes in contact with each other, whereas overload occurs when the number of electrical equipment connects to the same socket. Q.
What are the 3 requirements for a simple circuit?
Fuses: Fuses or circuit breakers are the best friend to prevent short circuits. A circuit trips during an overload or low electrical resistance and protects the lines from getting shorted. Thus, preventing internal short circuits is easier if you install fuses.
What are the causes of short circuit Class 7?
Fuse wire is used in electric circuits to prevent the excess current flowing into the circuit and therefore preventing the appliances from getting damaged. When a short circuit occurs the fuse blows thus limiting the damage to the connected devices.
Why do circuits get overloaded?
The current in a circuit depends on the rating of the appliances connected to it. If the total current drawn through a wire by the appliances connected to it exceeds the safety limit for that wire, it gets overheated. This is known as overloading.
How short circuit occurs in an electric fuse Class 7?
In mains circuits, short circuits may occur between two phases, between a phase and neutral or between a phase and earth (ground). Such short circuits are likely to result in a very high current and therefore quickly trigger an overcurrent protection device.
What is difference between overloading and short circuit?
The long path for the energy to flow back to ground is on the intended circuit. But when a shorter path is provided, electricity naturally seeks this route—the path of least resistance. The electricity immediately changes its course to head to ground on this shorter, easier path. Thus, the term short circuit.
What is short circuit How can it be prevented?
A short circuit happens when the current does not travel the intended path of the electrical circuit. A current is the flow of electricity. The current's pressure or strength, called the voltage, gets too high, which can result in an electrical fire.
Why is a fuse wire necessary in a circuit?
A Fuse is usually a short piece of wire. The Fuse is made up of a material which has high resistivity and low melting point, so that it melts down due to overheating of the wire during high current flow. The thickness of the Fuse wire is determined based on the amount of current flow in the circuit.
What is overloading Class 10?
In electronics, a circuit is a complete circular path that electricity flows through. A simple circuit consists of a current source, conductors and a load. The term circuit can be used in a general sense to refer to any fixed path that electricity, data or a signal can travel through.

What is a short circuit Grade 5?
A short circuit occurs when the current finds a way to bypass the appliance on a path that has little or no resistance—for example, where frayed insulation bares a wire and allows it to touch the frame of the appliance, so the current can flow straight to the ground.
What is fuse class 12?
