Question

The equivalent resistance of a parallel combination of two resistors 30 ohm and 60 ohm

Answer 1

equivalent resistance
= 30*60/30+60
=1800/90
=20 ohm

Answer 2

Hey Mate!

Here is your answer.....................

The equivalent resistance of a parallel combination of two resistors 30Ω & 60Ω.

(R1 * R2) / (R1 + R2)

(30*60) / (30+60)

1800 / 20

20Ω
