Wire resistance 1 (2 Circuit breaker Bulb 200 120 V Micro- Wave Toaster oven 20 n 16 (2

Req = 1 + (20 II 16 II 20)

= 1 + (10 II 16)
=7.154 ohm

A) I = V/Req = 120/7.154 A = 16.77 A

B) V' = V - I*R

=120 - 16.77*1 = 103.226V

current through bulb = 103.226/20 = 5.16A

C) current through oven = 103.226/16 =6.45A

D) current through Toaster = 103.226/20 = 5.16A

E)Power used by bulb = I2*R = (5.16)2*20 =532.78 W

F) Power used by oven = (6.45)^16 =665.64W

G)Power used by toaster = (5.16)^2*20 = 532.78W
