AC Impedance. Then the effective power consumed by an AC resistance is equal to the power consumed by the same resistor in a DC circuit. Many AC circuits such as heating elements and lamps consist of a pure ohmic resistance only and have negligible values of inductance or capacitance containing on impedance.

Amplitude of an AC Waveform. Sometimes, alternating waveforms are given a peak to peak, Vp p value and this is simply the distance or the sum in voltage between the maximum peak value, Vmax and the minimum peak value, Vmax during one complete cycle.

An AC circuit is the one in which the source of the circuit is of alternating current rather than DC (Direct current). At the start of the tutorial a brief introduction of AC (alternating current) is provided after that a simple AC circuit is implemented in PSPICE and the results were analyzed precisely.

This physics video tutorial explains the basics of AC circuits. It shows you how to calculate the capacitive reactance, inductive reactance, impedance of an RLC circuit and how to determine the ...

Capacitive in an AC Circuit Tutorial The capacitor opposes the flow of ac current, as a resistor does in a dc circuit. This opposition is called capacitive reactance, Xc.

Learn about Electromagnetic Induction and AC Circuits in this tutorial organized for easy follow up and based on content created by world class educators.

However, in AC circuits this ratio of voltage to current depends upon the frequency and phase difference or phase angle ( φ ) of the supply. So when using resistors in AC circuits the term Impedance, symbol Z is the generally used and we can say that DC resistance = AC impedance, R = Z.

Power in AC Circuits – a Tutorial. In a direct current circuit, the power consumed is simply the product of the dc voltage times the DC current, VxI and is measured in watts. However, we can not calculate it in a similar manner for reactive AC circuits. Electrical power is the “rate” at which energy is being consumed in a circuit...

AC circuits as the name (Alternating Current) implies are simply circuits powered by an Alternating Source, either voltage or current. An Alternating Current or Voltage , is one in which the value of either the voltage or the current varies about a particular mean value and reverses direction periodically.

Vol. II Alternating Current (AC) AC is produced by generators in power stations and can be found in homes, radio equipment, car alternators, and even synthesizers. AC voltage has several advantages over DC voltage (generation and transmission, transformer voltage increase decrease, electromagnetic emissions, etc.),...
