What is alternating current (AC)?

common problems 3970

Alternating current (AC) is a type of electric current whose polarity reverses periodically and whose amplitude varies continuously over time. AC power is often used in businesses and homes because it is cheaper and more efficient to generate and transmit than direct current (DC) power. During transmission, a transformer can reduce power losses by increasing or decreasing the voltage of the AC line.

Alternating current (AC) is a form of household electricity - it is used when consumers plug household appliances such as televisions and other devices into wall outlets. AC power can be converted to direct current for use in almost any electronic device.

    The article will cover the basics of impedance and points of measurement. Impedance is the resistance of an AC circuit and is invisible. Therefore, it must be measured using a specialized measuring instrument such as an impedance tester. People who have never touched an impedance tester before may be more concerned about how to use it and what to look for when using it. Therefore, this article will present in an easy-to-understand way the...

  • How does a spectrum analyzer work?

    A signal that looks very complex in the time domain behaves quite differently in the frequency domain. Time domain measurements show an impure sine wave. Without frequency domain measurements, it is still impossible to know the source and frequency of the second harmonic. Spectral analysis can show the spectral components individually, thus revealing the source of the interference. The information provided in the time domain (e.g., the signal pulse on...
