Question

Four resistors of 100 ohm each are connected in parallel .theit equivalent resistance will be??

Answer 1

Answer: If R = 100 ohm

So By using Formula

1/Rp = 1/r1 +1/r2+1/r3+1/r4

Putting Value

1/Rp = 1/100+1/100+1/100+1/100

=4/100 = 0.04 Ohm

Answer 2

Answer:

Explanation:

let the equivalent resistance be R

1/R=4 times of 1/100 [Since (1/r+...+1/r)×4]

1/R=4×1/100=1/25

R=25ohm
