Question

resistors having resistance of 15,20,10 Ohms are connected in parallel. What is the effective resistance in the circuit​

Answer 1

Step-by-step explanation:

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

=> 1/R = (4 + 3 + 6)/60

=> 1/R = 13/60

=> R = 60/13 = 4.62 ohms

Answer 2

Step-by-step explanation:

1/R=1/r1+1r2+1/r3

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

1/R=13/60

R=4.62ohm
