Pure R, L and C Circuits

In the graphical representation of e.m.f. ' $e$ ' and current ' $i$ ' versus ' $\omega t$ ' 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

Show answer and solution

Answer: (c)

Emf and current reaching zero, maximum and minimum together means zero phase difference.
Only a pure resistor gives $e$ and $i$ in phase; L and C give $\frac{\pi}{2}$ .
So the answer is (c) pure resistor.
