## How to Figure KVA of a Transformer: Transformer KVA Calculator

Learn how to figure KVA of a transformer by using the online Transformer KVA Calculator. Also, learn Why Transformer Rating is in KVA Not in KW?

## Current Transformer Classification based on Four Parameters

One can discern parameters that define their use and function in the electrical circuit
or the transformer’s circuit itself among the many features of transformers. We
therefore identify several factors that characterize the based on the designation of
the circuit and the circuit of the transformer.

## Explain BJT Transistor construction and working principle

Explain the working principle and construction of BJT Transistor and Symbol. A transistor can work as digital switch or an amplifier.

## Zener Voltage Pass Regulator Explained with Example

A Zener Diode is a special purpose diode used for voltage regulation in reverse bias. Zener diode work under breakdown region for typical operation. A minimum current of Zener knee current must be maintained to keep the voltage regulated.

## 3 Methods of testing a diode with multimeter and oscilloscope

Testing a diode with a digital multimeter in two ways, diode testing portion, and ohmmeter. A diode test is considered passed if it shows low resistance/voltage drop on forward bias and high resistance/voltage drop in reverse bias. A diode curve tracer uses an oscilloscope for VI characteristics graph.

## Diode Voltage Doubler Circuit with Tripler and Quadrupler Explained

Voltage Multipliers are electric circuits to increase the voltage by a factor of two, three or four in case of Voltage Doubler, Tripler or Quarple respectively. The Voltage multiplier circuit uses capacitors and resistors to enhance the voltage level.

## Forward Bias Diode and Reverse Bias Diode Characteristic Graph

A diode can be connected in forward and reverse bias with a source. In Forward bias connection, a diode conducts current like a closed switch. Where in reverse bias, a diode blocks current like an open switch.

## Difference between Alternating Current and Direct Current

Alternating current (AC) is the type of electrical current which changes its direction and magnitude every moment.

## How do Capacitors Add in Series: Capacitor in the Series Calculator

Capacitors can be connected in series to achieve the desired capacitance. The capacitance of series connection decreases and that of parallel connection increases.

## Difference between Ideal and practical, Voltage and Current Source

In contrast to a practical voltage source, an imaginary deal source provide constant voltage regardless of load current because of no internal resistance. While ideal current source provides a constant current regardless of load current.
