Question

in a parallel circuit there are four resistors with 10 ohm,10 ohm,3 ohm and 30 ohm if the current passed is 1.2 amperes then the current passed through I2 is​

Answer 1

Answer:

Parallel Resistance = 1/ (1/R1 + 1/R2 + 1/R3)

1/ (1/10 + 1/15 + 1/30)

= 1/ (3 + 2 + 1)/30 = 1/ (6/30)

= 30/6

= 5 Ohms

Total Current = V/R = 24/5

= 4.8 A

Current in R1 = 24/10 = 2.4 A

Current in R2 = 24/15 =1.6 A

Current in R3 = 24/30 = 0.8 A

Check: 2.4 + 1.6 + 0.8 = 4.8 A = Total Current…looks good!
