Electrical Circuits

Front

What is a circuit?

Back

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

Front

What is the role of a conductor in an electrical circuit?

Back

A conductor is a material that allows electricity to flow through it, facilitating the movement of electric current.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it, preventing the movement of electric current.

Front

Give an example of a common conductor of electricity.

Back

Copper is a common conductor of electricity.

Front

What is the function of wires in a circuit?

Back

Wires provide a pathway for electric current to travel from one component of the circuit to another.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow through it, while an insulator does not allow electricity to flow.

Front

What is the purpose of a power source in a circuit?

Back

The power source provides the electrical energy needed to drive the current through the circuit.

Front

What happens when a circuit is open?

Back

When a circuit is open, the flow of electric current is interrupted, and the circuit cannot function.

Front

What is a load in an electrical circuit?

Back

A load is a component that consumes electrical energy, such as a light bulb or resistor.

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, expressed as V = IR.
