Electro Magnetic Induction And Alternating Currents Question 7

Question: An alternating voltage is connected in series with a resistance R and an inductance L If the potential drop across the resistance is 200 V and across the inductance is 150 V, then the applied voltage is [CPMT 1990]

Options:

A) 350 V

B) 250 V

C) 500 V

D) 300 V

Show Answer

Answer:

Correct Answer: B

Solution:

The applied voltage is given by $ V=\sqrt{V_{R}^{2}+V_{L}^{2}} $ $ V=\sqrt{{{(200)}^{2}}+{{(150)}^{2}}} $ $ =250\ volt $
