Question

A voltage source of 300 V has internal resistance of 4Ω and supplies a load having the same resistance. The power absorbed by the load is?

(a) 1150 W

(b) 1250 W

(c) 5625 W

(d) 5000 W

The question was posed to me in an interview for internship.

This interesting question is from Voltage and Current Sources in chapter Circuit Elements and Kirchhoff’s Laws of Network Theory

Answer 1

The correct choice is (c) 5625 W

For explanation I would say: Power absorbed = I^2R.
