(Express your answer to two significant figures.) A Submit 3) Determine the current in the resistor. R2 (Express your answer to two significant figures,) A submit

Explanation / Answer

A)Req =R1*R2/(R1+R2) + R3 =20*15/(20+15) +8 =16.57 ohm

Itotal =V/Req =5/16.57 =0.3017A =I3

C)I2 =R1/(R1+R2)*Itotal =20/35*0.3017 =0.1724 A

B)I1 =Itotal -I2 =0.3017-0.1724 =0.1293A

D) power dissipated P =I^2*R

=>P1 =0.1724^2*20 =0.5944W

P2 =0.1293^2*15=0.2508W

P3 =0.3017^2*8 =0.7281 W
