Electric Circuits

Front

What is voltage in a circuit?

Back

The energy difference per unit charge between two points.

Front

What is a series circuit?

Back

A circuit where components are connected end-to-end, so the current flows through each component one after another.

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

What is current?

Back

The flow of electric charge in a circuit, measured in amperes (A).

Front

What is resistance?

Back

The opposition to the flow of electric current, measured in ohms (Ω).

Front

What is a complete circuit?

Back

A closed loop that allows current to flow, consisting of a power source, conductors, and a load.

Front

What happens if there is a break in a series circuit?

Back

The entire circuit stops working because the current cannot flow.

Front

What happens if there is a break in a parallel circuit?

Back

Other paths in the circuit can still allow current to flow, so some components may still work.

Front

What is a load in an electric circuit?

Back

A device that uses electrical energy, such as a light bulb or motor.

Front

What is a battery?

Back

A device that stores chemical energy and converts it to electrical energy to provide voltage in a circuit.
