Question

Three resistors having resistance of 15 Ω, 20 Ω and 10 Three resistors having resistance of 15 Ω, 20 Ω and 10 Ω are connected in parallel. What is the effective resistance in the circuit? * in parallel. What is the effective resistance in the circuit? *​

Answer 1

Answer:

4.61 ohm

Explanation:

Let R1=15 ohm

R2=20 ohm

R3=10 ohm

In parallel connection,

=> 1/Rs=1/R1 +1/R2 +1/R3

=> 1/Rs=1/15 +1/20 +1/10

=> 1/Rs=(4+3+6)/60 (taking L.C.M=60)

=> Rs= 60/13

=>. Rs= 4.61 ohm
