Question

In Figures 28.4 and 28.6, let R_1 = 14.0 Ohm, let R_2 = 22.0 Ohm, and let the battery have a terminal voltage of 38.0 V. (a) In the parallel circuit shown in Figure 28.6, to which resistor is more power delivered? R_2 R_1 (b) Calculate the sum of the power (^2R) delivered to each resistor. Calculate the power supplied by the battery (I Delta V). W (c) In the series circuit, which resistor uses more power? R_2 R_1 (d) Calculate the sum of the power (I^2 R) used by each resistor. Calculate the power supplied by the battery (I Delta V). W (e) Which circuit configuration uses more power? parallel series

Explanation / Answer

According to the given problem,

A) Answer: R1 as P = V2/R and R1<R2

B) P1 = 382/14 = 103.143 W and P2 = 382/22 = 65.63W

Sum = 168.78W

C)Answer: R2 as P = I2*R and I = 38/[14+22] = 1.056A and R2>R1

D) P1 = 1.0562*14 = 15.6W and P2 = 1.0562*22 = 24.5W

Sum = 40.11W

E ) BY D and B you can say Parallel
