Question

In a network consisting of linear resistors and ideal voltage source, if the value of resistors are doubled, then voltage across each resistor ___________

(a) increases four times

(b) remains unchanged

(c) doubled

(d) halved

I had been asked this question in an internship interview.

I want to ask this question from Voltage and Current Sources topic in chapter Circuit Elements and Kirchhoff’s Laws of Network Theory

Answer 1

The correct answer is (b) remains unchanged

The explanation is: Even on changing the values of linear resistors, the voltage remains constant in case of ideal voltage source.
