Problem

A student draws the voltage phasors for a series RLC circuit to the scale

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

. The phasor for the resistive voltage drop measures

6\,\text{cm}

along the horizontal axis. If the rms current in the circuit is

5\,\text{A}

, the resistance of the circuit is a)

30\,\Omega

12\,\Omega

24\,\Omega

34\,\Omega
