Calculate the power dissipated in R1 R2 and RSolutioniI3 I1

Calculate the power dissipated in R_1, R_2 and R.

i)I3 = I1+i2

ii) 13 - 3 i3 - 12 - i1*1 = 0

i1 + 3 i3 =1

iii)12 + 3 i3 - 14 + 2 i2=0

2 i2 + 3 i3 = 2

solving these eq

i1 = -1/11 , i2 = 5/11 , i3 = 4/11

Power dissipated in

a)R1 = i1^2 * R1 = 1/121 =8.264 mW

b)R2 = i2^2 * R2 = 0.413 W

c)r3 = 0.397 W
