Question

Resistors having resistances of 15 ,20,and 10 are connected in parallel,what is the effective resistance in the circuit?
plz give me answer​

Answer 1

Answer:

Effective resistance in the circuit= 4.62 ohm

Explanation:

Given data:-

R1 = 15 ohm, R2 = 20 ohm, R3 =10 ohm

Solution:-

We have,

1/Rp = 1/R1 + 1/R2 + 1/R3

= 1/15 + 1/20 +1/10

= 13/60

Rp = 60/13 = 4.62 ohm

Answer 2

Answer:

4.615 ohm

Explanation:

The total resistance in parallel combination is the sum of the reciprocal of the individual resistance

1/R = 1/10+ 1/15+ 1/20= 13/60

R = 60/13= 4.615 ohm
