Electricity and Circuits Quiz

What is resistance and why does it occur?

Investigate the relationship between current, potential difference (p.d.), and resistance for a resistor and filament lamp.

Test series and parallel circuits using resistors and filament lamps.

What is meant by power? Define power and state its units. Describe how power is related to energy transferred in joules. Describe how to calculate power when you know the current and potential difference.

Describe the difference between the live and neutral wire. Explain how earth wires and fuses make circuits safer. State the potential differences between the earth, neutral, and live wires.

Complete the energy transfer diagrams for a ball bearing fired from a catapult.

Complete the energy transfer diagrams for a remote controlled car.

How does adding additional bulbs to a series circuit affect the brightness of the bulbs? Why does this happen?

Describe the cause of electrical resistance in wire.
