Question

Write the equivalent resistance of three resistors in (a) parallel (b) series

Answer 1

Answer:

Resistance in parallel

1/R=1/R¹+1/R²+1/R³

Resistance in series

R=R¹+R²+R³

Answer 2

Resistance in parallel combination -

For resistors R1 , R2 & R3 connected in parallel combination

Equivalent Resistance 'R' is given as

1/R = 1/R1 + 1/R2 + 1/R3



For the same resistors connected in series
Equivalent Resistance 'R' is given as

R = R1 + R2 + R3
