Alternating Current * Learning Outcomes
... While in direct current (d.c.), current always flows in the same direction (positive to negative), alternating current (a.c.) continuously changes directions. The current does not change direction abruptly – it is a gradual process of acceleration, fitting models of waves and SHM. Thus when we ...

... We also know that i3 = ½ of i2 = 1 mA. Using Ohm’s law, solve for the resistance values. R1’s resistance is the voltage across it by the current through it. This gives R1 = 2 kΩ because V/mA = kΩ. R2’s value is 3 kΩ. For v3 and v4, we know the total voltage across the two is v4 + v3. From the given ...

Here we`ll find the initial value of capacitor voltage - Rose
... Note that ic(0) is actually the opposite of the inductor current. So ic(0) = -20 mA. Substitute that and the capacitance into the equation for dvc(0) / dt. This says that the voltage’s initial rate of change is -10,000 V/s. This large number indicates a rapid rate of change. It’s not necessarily a “ ...

This article provides a more detailed explanation of p–n diode behavior than that found in the articles p–n junction or diode.A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p-type semiconducting layer to an n-type semiconducting layer. Semiconductor diodes have multiple uses including rectification of alternating current to direct current, detection of radio signals, emitting light and detecting light.
