## A Brief Guide About Electronic Oscillator and their Different Types

An oscillator is a circuit that generates a repetitive, alternating waveform without any external input. It converts DC power from a source into an alternating waveform of a specific frequency and voltage level.

## 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.

## Derivation of Diode Current Equation, Calculator, and Example

The diode current equation depends on the dark saturation current, the charge of an electron, and external voltage. We also provide a calculator for the diode current equation.

## 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.

## Difference between Alternating Current and Direct Current

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

## 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.

## Voltage to Current Source Transformation Theorem

Source transformation or conversion is a technique to replace a voltage source with a current source for circuit simplification and vice versa.

## Norton Theorem with Examples: How to Use Norton Theorem?

Norton Theorem reduces any two port circuit to a Norton Resistor, a load resistor, and a current source in parallel. Where Thevenin Theorem incorporates voltage source in series.
