Question

All the resistance given below are of $1\Omega$. Find the value of I ?

• A. 4 A
• B. 2 A
• C. 3 A
• D. 1 A

Answer 1

The correct option is A

4 A

All the resistors 2R, R , 2R are connected in parallel.
So,$\frac{1}{R_{eqv}}=\frac{1}{2R}+\frac{1}{R}+\frac{1}{2R}$
$R_{eqv}=\frac{1}{2}\Omega$
V =IR
I =4 A
