Question

(20) Calculate the equivalent resistance
of a wire of resistance 10 ohm is
divido a into to two equal parts and
connected in parallel ? [2018]​

Answer 1

Answer:

2.5 ohm

Explanation:

in parallel,

1/Equivalent resistance equals 1/R1 + 1/R2

In this case, R1= R2= 5 ohm, since 10 ohm wire is divided into two equal parts

hence, 1/R= 1/R1 + 1/R2

=1/5 + 1/5

=2/5

therefore, R= 5/2= 2.5 ohm
