2 In this experiment, you will investigate the resistance of a parallel combination of resistance wires. You have been provided with two metre rules with resistance wires attached. (a) (i) • A, B and C are crocodile clips. Connect A to the soldered joint as shown in Figure 2.1. • Connect B and C as shown in Figure 2.1. soldered D joint B metre rule B A C resistance wire D C Figure 2.1 • Adjust the position of B so that the length L of wire between A and B is approximately 50 cm. • Determine L. L = ............................................................... • Estimate the percentage uncertainty in your value of L. Show your working. percentage uncertainty = ........................................................... % [1] (ii) • Adjust the position of C so that the length of wire between A and C is also L. • The distance from the end of the metre rule to B is D . B The distance from the end of the metre rule to C is D , as shown in Figure 2.1. C Measure and record D and D . B C D =
