Electric Power Single and Three Phase Power Active Reactive Apparent

Complex Power It is very conceptual and essential to understand. For establishing the expression of complex power , we have to first consider a single phase network that’s voltage and current can be represented in complex form as V.e jα and I.e jβ . Where α and β are angles that voltage vector and c

Ceramic Capacitor: What is it?

What is a Ceramic Capacitor? A ceramic capacitor is the most commonly used capacitor in an electronic circuit. A ceramic capacitor is used due to its small physical size and large charge storage capability. The ceramic capacitor gets its name from its use of ceramic as a dielectric medium. We call t

Parallel Plate Capacitor: Definition, Formula, and Applications

A parallel plate capacitor is a device that can store electric charge and energy in the form of an electric field between two conductive plates. The plates are separated by a small distance and are connected to a voltage source, such as a battery. The space between the plates can be filled with air,

Energy Stored in Capacitor

While capacitor is connected across a battery , charges come from the battery and get stored in the capacitor plates. But this process of energy storing is step by step only. At the very beginning, capacitor does not have any charge or potential. i.e. V = 0 volts and q = 0 C. Now at the time of swit

Discharging a Capacitor (Formula And Graphs)

What is Discharging a Capacitor? Discharging a capacitor means releasing the charge stored within the capacitor. Let’s go over an example where a capacitor is discharged. We connect a charged capacitor of capacitance C farad in series with a resistor of resistance R ohms. We then short circuit this

Transient Behavior of Capacitor

When a voltage is suddenly applied across a capacitor , which are previously uncharged, electrons shifting from source to capacitor to source start immediately. In other words, accumulation of change in the capacitor starts instantly. As the charge accumulating in the capacitor increases, the voltag

Quality Factor of Inductor and Capacitor

Quality Factor of Inductor Every inductor possesses a small resistance in addition to its inductance. The lower the value of this resistance R, the better the quality of the coil. The quality factor or the Q factor of an inductor at the operating frequency ω is defined as the ratio of reactance of t
