Electricity Review

Front

What is voltage?

Back

Voltage is the force or push of electrons in a circuit, measured in units called Volts.

Front

What are conductors?

Back

Conductors are materials that allow electric current to pass through them.

Front

What is static electricity?

Back

Static electricity is the build-up of electric charge on the surface of objects, which can cause phenomena like lightning.

Front

What happens to electric charges that are alike?

Back

Electric charges that are alike repel each other.

Front

What does a complete circuit do?

Back

A complete circuit allows electric current to flow, enabling devices like light bulbs to function.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to pass through it.

Front

What is the unit of electric current?

Back

The unit of electric current is Amperes (Amps).

Front

What is the relationship between voltage, current, and resistance?

Back

This relationship is described by Ohm's Law: Voltage (V) = Current (I) x Resistance (R).

Front

What is the effect of a broken circuit?

Back

A broken circuit prevents electric current from flowing, causing devices like light bulbs to not light up.

Front

What is the role of a switch in an electric circuit?

Back

A switch controls the flow of electric current by opening or closing the circuit.
