DC (RW/JG) 304039/2 © UCLES 2022 [Turn over You may not need to use all of the materials provided. 1 In this experiment, you will investigate an electrical circuit. You have been provided with a wooden strip with a wire attached. (a) Measure and record the length L of the wire between the nails on the wooden strip, as shown in Fig. 1.1. nail wooden strip wire nail Fig. 1.1 L = [1] (b) You have also been provided with a wire labelled A with crocodile clips at its ends. ● Set up the circuit shown in Fig. 1.2. 1.5 V d.c. Y V1 V2 Fig. 1.2 ● F, G, H and J are crocodile clips. The distance between one of the nails and H is d, as shown in Fig. 1.2. Attach H to the wire on the wooden strip so that d is approximately 20 cm. ● Close the switch. ● Record the value of d and the voltmeter readings V1 and V2. ● Open the switch. d = ............................................................... V1 = ............................................................... V2 = ............................................................... [2] (c) Increase d by placing H at different positions on the wire and record V1 and V2. Repeat until you have six sets of readings of d, V1 and V2. Include your values from (b). Record your results in a table. Include values of V2 d and d 2 in your table. V1 [8] (d) (i) Plot a graph of V2 d on the y-axis against d 2 on the x-axis. [3] V1 (ii) Draw the straight line of best fit. [1] (iii) Determine the gradient and y-intercept of this line. gradient = ............................................................... y-intercept = ............................................................... [2] (e) It is suggested that the quantities V1, V2 and d are related by the equation V2 d = Pd 2 + Q V1 where P and Q are constants. Using your answers in (d)(iii), determine values for P and Q. Give appropriate units. P = ............................................................... [Show More]
