MHT CET · Physics · Alternating Current
An a. c. voltage is applied to pure inductor. The current in the inductor
- A leads the voltage by \(\left(\frac{\pi}{4}\right)^{\mathrm{c}}\)
- B leads the voltage by \((\pi / 2)^c\)
- C lags behind the voltage by \(\left(\frac{\pi}{2}\right)^c\)
- D lags behind the voltage by \(\left(\frac{3 \pi}{4}\right)^{\mathrm{c}}\)
