Electric Circuits

What is the role of a battery in a circuit?

• It serves as a source of electric current.

• It acts as a resistor to limit current flow.

• It stores energy for future use.

• It converts AC to DC power.

What is resistance in an electric circuit?

• The measure of voltage in a circuit.

• The opposition to the flow of electric current.

• The speed at which electricity travels.

• The amount of power consumed by a device.

What is a circuit?

• A closed loop that allows electricity to flow.

• A device that stores electrical energy.

• A pathway for sound waves to travel.

• A type of electrical resistance.

What is the unit of measurement for current?

• Volts (V)

• Ohms (Ω)

• Amperes (A)

• Watts (W)

What is current in an electric circuit?

• The flow of electric charge.

What is a conductor?

• A material that allows electricity to flow through it easily.

• A material that blocks electricity from flowing.

• A type of electrical device that stores energy.
