Explanation / Answer

Here,

part A)

Voltage , V = 9.2 V

current in resistance R1 = V/R1

current in resistance R1 = 9.2/6 = 1.533 A

current in resistance R1 is 1.533 A

as the resistance R2 and R3 are in series

current in resistance R2 = current in resistance R3 = V/(R2 + R3)

current in resistance R2 = current in resistance R3 = 9.2/(6 + 4)

current in resistance R2 = current in resistance R3 = 0.92 A

for the current in R4 = V/R4

current in R4 = 9.2/10

current in R4 = 0.92 A

part B)

for the power delivered

P1 = 1.533^2 * 6 = 14.1 W

P2 = 0.92^2 * 4 = 3.39 W

P3 = 0.92^2 * 6 = 5.08 W

P4 = 0.92^2 * 10 = 8.46 W

part C)

for the equivalent resistance

Ptotal = P(equivalent)
