Question

Two resistors of 30Ω and 70Ωare connected in parallel.Calculate their equivalent resistance.

Answer 1

R1 = 30 ohm

R2 = 70 ohm

$= \frac{1}{r1} + \frac{1}{r2} \\ = \frac{1}{30} + \frac{1}{70} \\ = \frac{7 + 3}{210} \\ = \frac{10}{210} \\ = \frac{1}{21}$

Their equivalent resitance is 1/21 ohm

Answer 2

Answer:

0.36ohm

Explanation:

step by step explained

as the resistors are connected in parallel.

so 1/30+1/70 = 70+30/210

=100/210

=10/21

=0.36 ohm

may i have helped u !!
