For the circuit shown below, V₁ = 40V when R is 10Ω. When R is 0 Ω, the value of V₂ will be —

1. 40V
2. 30V
3. 20V
4. 10V

Correct Option: A

The given circuit:

From given circuit we conclude that voltage at node 1, i.e. V₁ is independent from the resistance R. When R is 0 Ω, the value of V₂ will be 40V.
