Problem

In a scale drawing of the voltage phasors of a series circuit operating at

50\,\text{Hz}

, the following measurements are obtained: • Horizontal resistive voltage:

5\,\text{cm}

to the right • Vertical reactive voltage

(V_L - V_C)

3\,\text{cm}

upward Scale:

1\,\text{cm} = 20\,\text{V}

The rms current is

4\,\text{A}

and the inductance is

0.15\,\text{H}

. The capacitance of the capacitor in the circuit is closest to a)

50\,\mu\text{F}

99\,\mu\text{F}

70\,\mu\text{F}

220\,\mu\text{F}
