when voltage drops what happens to current?
when voltage drops what happens to current?
Last answer:
This depends on the power of the source.If power is kept constant then the voltage increases with decrease in current (P=VI) .But if lets say the source is replaced by new batteries then the current increases (V=IR).

What happens to current flow in a capacitive circuit when the DC voltage across the capacitor is
What happens to current flow in a capacitive circuit when the DC voltage across the capacitor is approximately equal to the source voltage?
Last answer:
Capacitor always charges up to the voltage of source. When the capacitor is charged to same as source voltage then there is no current flowing through the capacitor. The current through the capacitor is called displacement current.

why is it that when the frequency of a voltage in an inductor increases current decreases?
A sine wave voltage is applied across an inductor. When the frequency of the voltage is decreased, the current decreases.
Last answer:
The question seems to be wrong. Increase in frequency would actually decrease the current through the Inductor. This happens because inductive reactance Xl is directly proportional to frequency. And if frequency increases the value of Xl would ... vice versa. Xl= 2*pi*f*L I=E/Z Z=sqrt(R^2+Xl^2)
