Question

The equivalent resistance of two resistors of resistance 4 and 12 ohms connected in parallel is
a) 16 ohm
(b) 8 ohm
(c) 3 ohm
(d) 2 ohm​

Answer 1

Answer:

Answer

c) 3 ohm

here, 1/R=1/4 + 1/12

and by simplify

R=3

hope it helps

Answer 2

The total resistance of resistors connected in parallel is found by adding up the reciprocals of the resistance values.

The equivalent resistance is calculated as follows

1/Rₙ=1/R₁ + 1/R₂ + 1/R₃

In the given question, the resistance values given are

R₁= 4 ohms

R₂ = 12 ohms

1/Rₙ=1/R₁ + 1/R₂

=1/4 +1/12 = 3 ohms

Hence, the answer to the question is c) 3 ohms.
