Direct current is a flow of electric charge in only one direction and has a steady state of constant voltage in the circuit. Rectifiers, batteries,…
![RMS Value in AC Circuit](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14211.jpg)
The root mean square (RMS) value is a measure of the effective or average value of an alternating current (AC) waveform. In AC circuits, the voltage…
![Capacitor in an AC Circuit](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/13810.jpg)
A capacitor is charged by passing an electric current through it, which causes the plates to start accumulating an electrostatic charge. Since the…
