In the graphical representation of e.m.f. ' $e$ ' and current ' $i$ ' versus ' $\omega \mathrm{t}$ ' for an a.c. circuit, both emf and current reach zero, minimum and maximum value at the same time. The circuit element connected to the source will be
pure capacitor
combination of capacitor and inductor
pure resistor
pure inductor
Solution
Since the current and emf are in phase the circuit is purely resistive.
