## Homework Statement

An emf V

_{o}sinwt is applied to a circuit which consists of a self inductance L of negligible resistance in series with a variable capacitor C. The capacitor is shunted by a variable resistance R. Find the value of C for which the amplitude of the current independent of R.

## The Attempt at a Solution

We can use Phasor Algebra to make the problem easy. But I don't have any idea how to start.

Shall I take the equation V = jV

_{L}+ V

_{R}? , which comes out by taking V

_{R}along x-axis and V

_{L}along Y axis. If we use this equation then there is no capacitance anywhere.

Help me out!
