Question

three resistance 10ohm,15phm,30ohm,and 4.5 volt find it in ohm's law?​

Answer 1

Explanation:

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
