The CIrcuit

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow through it, consisting of a power source, conductors, and a load.

Front

What are the main components of an electrical circuit?

Back

The main components are a power source (like a battery), conductors (wires), and a load (like a light bulb or motor).

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, so the same current flows through all of them. In a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It can be expressed as V = I × R.

Front

What is the role of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit, helping to control the voltage and current levels.

Front

What is a switch and how does it function in a circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

What is a load in an electrical circuit?

Back

A load is any component in a circuit that consumes electrical energy, such as a light bulb, motor, or heater.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electricity is interrupted, and the devices in the circuit will not operate.

Front

What is a short circuit?

Back

A short circuit occurs when electricity flows along an unintended path with little or no resistance, which can cause overheating and damage.

Front

What is the function of a battery in a circuit?

Back

A battery serves as a power source, providing the necessary voltage to push electric current through the circuit.
