Predict/Calculate Black-Box Experiment You are given a sealed box with two electrical terminals. The box contains a 5 00-Ω resistor in series with either an inductor or a capacitor. When you attach an ac generator with an rms voltage of 0.750 V to the terminals of the box, you find that the current increases with increasing frequency. (a) Does the box contain an inductor or a capacitor? Explain. (b) When the frequency of the generator is 25 0 kHz, the rms current is 87 2 mA. What is the capacitance or inductance of the unknown component in the box?
