Fig. 10.1 shows a circuit that is used to find the resistance of a component. The diagram contains an ammeter marked "A", a voltmeter marked "V", a fixed resistor, a variable resistor, and connecting wires.
(a)[1]
On Fig. 10.1, put the letter R beside the fixed resistor to label it.
(b)[4]
Identify the quantity measured by each component. Write each quantity and the unit for each one in the correct section of Table 10.1.
(c)[2]
State how a wire's resistance depends on its length and its diameter.
