Explanation / Answer

a) equivalent resistance of combination R4, R5, R6

= R4 + R5 + R6

b) equivalent resistance of combination R3, R4, R5, R6

= [ R3 * (R4 + R5 + R6)] /  (R3 + R4 + R5 + R6)

c) equivalent resistance of combination R1, R2, R3, R4, R5, R6

Requ = R1 + R2 + [ R3 * (R4 + R5 + R6)] /  (R3 + R4 + R5 + R6)

d) Requ = 14 + 25 + [ 52* (61+ 76+ 67)] /  (52+ 61 + 76 + 67)

equivalent resistance = 80.44 ohm

e) delta V = I * R

f) delta V = 11.5 * 80.44

delta V = 925 V
