Ohm’s Law Homework (NAT5)
1.
Use this cartoon to explain Ohms Law and
the equation V =I x R, by explaining what
each “character is doing
(3)
2. A current of 0.5A flows through a lamp when it is connected to a 6V
battery. What is the resistance of the lamp?
3.
(2)
The following results are obtained from an experiment using a 9v variable power
supply in the circuit below:
0- 9v
a)Plot a graph of these results
b) from the graph calculate the
resistance of the resistor (3)
