Electro Magnetic Induction And Alternating Currents Question 406

Question: The diagram shows a capacitor C and a resistor R connected in series to an ac source. $ V_{1} $ and $ V_{2} $ are voltmeters and A is an ammeter Consider now the following statements

I. Readings in A and $ V_{2} $ are always in phase II. Reading in $ V_{1} $ is ahead in phase with reading in $ V_{2} $ III. Readings in A and $ V_{1} $ are always in phase which of these statements are/is correct

Options:

A) I only

B) II only

C) I and II only

D) II and III only

Show Answer

Answer:

Correct Answer: B

Solution:

  • In RC series circuit voltage across the capacitor leads the voltage across the resistance by $ \pi /2 $
