Problem

In a scale drawing of the voltage phasors of a series circuit operating at 50 Hz50\,\text{Hz}, the following measurements are obtained: • Horizontal resistive voltage: 5 cm5\,\text{cm} to the right • Vertical reactive voltage (VL−VC)(V_L - V_C): 3 cm3\,\text{cm} upward Scale: 1 cm=20 V1\,\text{cm} = 20\,\text{V} The rms current is 4 A4\,\text{A} and the inductance is 0.15 H0.15\,\text{H}. The capacitance of the capacitor in the circuit is closest to (a) 50 μF50\,\mu\text{F} (b) 99 μF99\,\mu\text{F} (c) 70 μF70\,\mu\text{F} (d) 220 μF220\,\mu\text{F}
