4.2 Energy, Power, and Resistance

Question 1

Define potential difference

Answer 1

work done by charge carriers which lose energy as they pass through a component in a circuit

Question 2

Define electromotive force

Answer 2

Work done TO charge carriers when they gain energy as they pass through a cell

Question 3

Draw an Light dependent resistor graph

Answer 3

-Y axis = Resistance
-X axis = light intensity
-Both values increasing
-Exponential curve downwards
