Question

Find the Curren using KVL

Answer 1

i1 = i2 + i3

(b - 18)/20.5 + ( b - 3 ) / 6 + ( b - 12 ) /8 = 0

48( b - 18 ) + 164 ( b - 3 ) + 123 ( b - 12 ) = 0

48b - 864 + 164b - 492 + 123b - 1476 = 0

335b - 2832 = 0

b = 2832/335

b = 8.4 V

- i1 = ( 8.4 - 18 / 20.5 )

i1 = 0.46 A

i2 = (8.4 - 3)/6

i2 = 0.9 A

i3 = (8.4 - 12)/8

i3 = -0.45 A
