Question

A resistance R placed in parallel with another resistance of 40π ,their equivalent resistance is 24π .the value of R is..............a)40π b)30π. c)60π​

Answer 1

Answer:

Explanation:

1/Re = 1/R1 + 1/ R2

1/R1= 1/Re - 1/R2

1/R1 = 1/24 - 1/40

1/R1= 5 - 3/120

1/R1 = 2/120

1/R1 = 1/60

R1= 60 ohm
