Electric Circuits

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load (like a bulb).

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What happens when a switch is closed in a circuit?

Back

Closing a switch completes the circuit, allowing electricity to flow and powering the devices connected.

Front

What is the function of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy when electricity flows through it.

Front

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

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across the same voltage source.

Front

What occurs if one bulb in a series circuit burns out?

Back

If one bulb in a series circuit burns out, the circuit is broken, and all bulbs will go out.

Front

What is resistance in an electric circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current, affecting how much current flows in the circuit.

Front

How does adding more batteries affect a circuit?

Back

Adding more batteries increases the voltage, which can increase the flow of electricity and make bulbs brighter.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or glass.
