Question

A combination of three resistance has been shown here. effective resistance between the points a and b is
A)8 ohm b) 4ohm c )2ohm d)1ohm

Answer 1

Answer is option A.8 ohm

Answer 2

The effective resistance is 8 ohm

(A) is correct option.

Explanation:

Given that,

First resistance $R_{1} = 4\ \Omega$

Second resistance $R_{2} =2\ \Omega$

Third resistance $R_{3}=2\ \Omega$

According to the figure,

We need to calculate the effective resistance

Using formula of resistance

$R=R_{1}+R_{2}+R_{3}$

Put the value into the formula

$R=4+2+2$

$R=8\ \Omega$

Hence, The effective resistance is 8 ohm.
