What is the phase difference between A.C emf and current in the following : Pure resistor, pure inductor and pure capacitor. |
Answer» (i) In pure resistor A.C. e.m.f and current are in phase with each other. (ii) In pure inductor, current lags behind the e.m.f. by an angle of `(pi)/(2)` (or) `90^(@)`. (iii) In pure capacitor, current leads the e.m.f by an angle `(pi)/(2)` (or) `90^(@)`. |
