Question

In the animation below, an inductor L is connected to an AC voltage source. A plot of the instantaneous current and voltage across the inductor versus time is shown at the bottom left, along with a phasor diagram for this circuit that updates along with the current and voltage plot. Instructions: Use the sliders to adjust the frequency, inductance and voltage amplitude. Click "start" to begin the animation. Click "start" to run the animation, and watch carefully as the plot is generated. Current is plotted in purple and voltage is plotted in tan. As the plot generates, the phasor diagram on the right rotates about the origin. In this diagram, the purple vector represents current and the tan vector represents voltage. The instantaneous value of each parameter is given by the y-component of the corresponding phasor vector. Click "start" again, observe the plot and phasor diagram carefully as both evolve, and verify that this is the case. In this purely inductive circuit, current and voltage are related by Ohm 's law. I = V/X_L V is given by delta V_max sin omega t and X_L is the inductive reactance given by the following equation. X_L = 2pi integral L The units of X_L are ohm s (ohm). Check all choices below that are correct. Increasing the frequency decreases the current. Increasing the inductance decreases the current. Voltage leads current. Changing the inductance does not affect the current. Current and voltage are in phase. Increasing delta V_max decreases the current. Changing the frequency does not affect the current. Increasing delta V_max increases the current. Increasing the inductance increases the current. Current leads voltage. Changing delta V_max does not affect the current. Increasing the frequency increases the current.
