Question

two resistors of 2 ohm are connected in parallel . find its equivalent resistance

Answer 1

$equivalent \: resistance = \frac{1}{r1} + \frac{1}{r2} \\ = \frac{1}{2} + \frac{1}{2} \\ = \frac{2}{2} \\ = 1ohm$

Answer 2

Answer:

two resistance are 2 ohm each

R =1/R1 +1/R2

R=1/2 +1/2

R= 2/2

R = 1 ohm
