24 Use Kirchhoff's laws to determine the currents /, 1 and in the circuit below. [6] 4.5V X a b c 25 The following circuit is used to compare two e.m.f.s. E 1.5V 0.40 S E 2092 r 1/ 0.85m 10 R -3.0V Y E The uniform resistance wire XY has a length of 1.00 m and radius 0.55 mm. The resistivity of the material of the wire is 1.1 x 10-6m. E, has an e.m.f. of 1.5V and internal resistance of 0.40 2. The current through E, is I. E has an e.m.f. of E and internal resistance of r. The movable contact J is adjusted so that the current flowing through E is zero. When this occurs, the length XJ is 0.85 m and the variable resistor has a resistance of 1.89. uniform resistance wire length 1.00m Calculate the resistance of wire XY. Calculate the current /. Calculate the potential difference across the length of wire XJ. d State the value of E. [3] [2] [2] [1] 24 Use Kirchhoff's laws to determine the currents /, 1 and in the circuit below.
