Question
The variation of the instantaneous current (I) and the instantaneous emf (E) in a circuit is as shown in fig. Which of the following statements is correct
- The voltage lags behind the current by / 2
- The voltage leads the current by / 2
- The voltage and the current are in phase
- The voltage leads the current by
The correct answer is: The voltage leads the current by / 2
At t = 0, phase of the voltage is zero, while phase of the current is i.e., voltage leads by

An ac source of angular frequency is fed across a resistor r and a capacitor C in series. The current registered is I. If now the frequency of source is changed to /3 (but maintaining the same voltage), the current in then circuit is found to be halved. Calculate the ratio of reactance to resistance at the original frequency
