Front

What causes certain objects to become temporary magnets?

Back

The domains aligning.

Front

What phenomenon causes magnetic striping in the ocean floor?

Back

The reversal of Earth's magnetic poles.

Front

What happens to the other light bulbs in a circuit if one bulb is removed?

Back

The other bulbs will stay on.

Front

Match the following terms to their correct units: Current, Voltage, Resistance.

Back

Current: Amps (A), Voltage: Volts (V), Resistance: Ohms (Ω).

Front

What happens when a glass rod is rubbed with silk?

Back

The silk has become negatively charged.

Front

Define 'Current' in the context of electricity.

Back

Current is the flow of electric charge, measured in Amperes (A).

Front

What is 'Voltage'?

Back

Voltage is the electric potential difference between two points, measured in Volts (V).

Front

Define 'Resistance' in electrical circuits.

Back

Resistance is the opposition to the flow of electric current, measured in Ohms (Ω).

Front

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

Back

Ohm's Law states that Voltage (V) = Current (I) x Resistance (R).

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be observed.
