1. Run the animation for the initial set of values. According to the resulting graph and phasor diagram, we would say that the voltage across the inductor ________ the current through the inductor by ________ degrees. 1.leads; 90 2.lags; 90 3.leads; 180 4.lags; 180 Click here to play animation

2. The voltage across the inductor and the current in the inductor are not in phase, but according to the two graphs, how do their frequencies of oscillation compare? 1.The frequency of the voltage is greater than the frequency of the current. 2.The frequency of the voltage is less than the frequency of the current. 3.The frequency of the voltage is equal to the frequency of the current. 4.Any of the above, depending on the value of the inductance.

3. In Active Figure 21.1, the maximum value of the current was independent of the voltage frequency. In this animation it is not. How does voltage frequency affect the maximum current and why does it do so? The greater the frequency, the ________ rapid the change in flux through the inductor coil and, according to Faraday's law, the ________ the opposing induced emf in the coil. 1.more; smaller 2.less; smaller 3.more; greater 4.less; greater Click here to play animation
