Zener Voltage Pass Regulator Explained with Example

July 4, 2022November 1, 2019 by Michal

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

July 4, 2022August 15, 2019 by Michal

Testing a diode

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

July 4, 2022August 9, 2019 by Michal

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

July 4, 2022December 25, 2018 by Shahab Yousafzai

forward bias and Reverse bias of diode

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

July 4, 2022August 6, 2018 by Michal

Capacitors in Series and parallel

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

February 11, 2024June 12, 2018 by Michal

Difference between ideal and practical 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

July 4, 2022June 3, 2018 by Michal

Source Conversion

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

Thevenin Theorem and Example: The Thevenin Equivalent Circuit

March 10, 2024May 29, 2018 by Michal

Thevenin Equivalent Circuit

According to Thevenin Theorem, a complex circuit is reduced to two resistor network, Thevenin Resistor, and Load resistor and a Thevenin Voltage source to avoid redundant computation to analyze a frequent changing resistor.
