PART A.
Suppose R, = 87.1 Q, R, = 29.2 Q, R3 = 50.2 0, R4 = 22.9 Q, R5 = 89 Q
and V = 918 V. If the switch is open, find the current through R4, in
Amperes.
PART B.
Suppose R, = 1.44 Q, R, = 8.5 N, R3 = 3.02 Q, R4 = 1.82 Q, R5 = 6.02 Q
%3D
and V = 544 V. If the switch is closed, find the current through R, , in
Amperes.
Expert Solution

Step 1
(A)
Given that the switch is open. R3 and the parallel connected R4 and R5 are in series, the combination of R3, R4 and R5 is parallel with R1. The combination of R1, R3, R4 is connected in series with R2.
Thus, the equivalent resistance of the circuit will be;
