Physics AQA Unit 2 Quiz: Electricity

Here is my fifth Unit 2 quiz, covering all the electricity topics.

?
How do we measure potential difference?
With a voltmeter connected in parallel
1 of 17
The difference between a series circuit and a parallel circuit is
a series circuit is a single pathway for an electric current whereas a parallel circuit gives more than one pathway for the electric current
2 of 17
What is measured in Ohms?
Resistance
3 of 17
What do we mean by resistance?
Opposition to current flow
4 of 17
What effect does reversing a potential difference across a filament lamp have?
Nothing happens
5 of 17
What is the equation for current?
p.d. of supply / total resistance
6 of 17
What component's resistance decreases as the temperature increases?

Good quiz :) made my day

Aparna

Report

Energy Transformed = Potential Difference x Current

Not, 

Potential Difference x charge.

Correct me if I'm wrong.

Aparna, its either Power = Potential Difference * Current

OR

Energy Transformed = Potential Difference * Charge
