Capacitance is much more difficult to measure than resistance. This problem shows one crude way to get that measurement done. Consider a 15 Ω resistor in series with an unknown capacitor. You can use a function generator like those in the studio to make a 20 volt rms signal at 6100 Hz. If a multimeter shows the rms current through the circuit to be 1.259 A, what is the capacitance of your capacitor?
