6 FAQs about [Alternating current capacitor inductor]

What is the difference between a capacitor and an inductor?

(Eq. AC.14: Voltage proportional to the slope of the current) This is essentially the opposite of the behavior that we saw with the capacitor. With a capacitor, the current is proportional to the slope of the voltage vs. time graph. With an inductor, the inductor voltage is proportional to the slope of the current vs. time graph.

What is alternating current (AC)?

Alternating current (ac) refers to systems in which the source voltage varies periodically, particularly sinusoidally. The voltage source of an ac system puts out a voltage that is calculated from the time, the peak voltage, and the angular frequency. In a simple circuit, the current is found by dividing the voltage by the resistance.

How does an inductor respond to an increase in current?

to the current through the inductor), and the inductor responds by acting as a battery, connected so as to cancel out some of the increase in current. It also acts as a resistor, too, as before. In (c), the current in the circuit is directed to the right, and is decreasing.

How does an inductor act as a resistor?

In (c), the current in the circuit is directed to the right, and is decreasing. This causes a decrease in magnetic flux through the coils of the inductor, and the inductor responds by acting as a battery, connected so as to cancel out some of the decrease in current. As before, it also acts as a resistor.
