Electronics – Electrical Unit Definitions
Definitions of basic measurement units in electricity and electronics. Ampere (A), Coulomb (C), Joule (J), Watt (W), Farad (F), Henry (H), Ohm (Ω), Siemens (S), Volt (V), Hertz (Hz), Radian, Angular frequency (w), Time (t)
RC High Pass Filter
An RC high pass filter allows only the passage of frequencies above the cut-off frequency (Fc) and eliminates frequencies above this frequency
12V 1A Power Supply Circuit
This 12V 1A power supply using zener diode and transistors allows us to obtain an output of approximately 11.4 volts with a very small percentage variation for a wide variety of loads.
Lie Detector Circuit Using Two Transistors
This simple lie detector consists of two transistors and other additional components and can detect if a person does not tell the truth (the person is lying), using two sensors placed directly on the skin.
How to use op amps with a single rail power supply?
How to use op amps with a single rail power supply?
Method #1: Voltage divider using two resistors. Method #2: Voltage divider using two Zener diodes.
Superposition Theorem – Example
The Superposition Theorem
The Superposition theorem states that the effect of two or more voltage sources in a resistor is equal to the sum of the individual effects of each source taken separately, replacing all the remaining voltage sources with short circuits.
What is Electrical Resistance? Obtaining a material’s resistance
The electrical resistance is a measurement of the opposition that offers a material to the passage of electrons (the electric current)
Semiconductor Diode – Bias – Operation – Diode Types
The semiconductor diode is the simplest semiconductor device and can be found in almost any electronic circuit. Diodes are manufactured with germanium and silicon (the most common).
How to make a Police Style Strobe Light Circuit?
This circuit shows the familiar lights which are used on police cars. It uses a 555 timer as a clock for the 4017B decade counter, two transistors and twelve LEDs
Second Right-Hand Rule – Electromagnetism
Second Right-Hand Rule. When a current flows through a conductive wire, a non-visible effect called the electromagnetic field is generated around it.
How to test Diodes and How to test Transistors using Multimeter?
How to test Diodes and how to test Transistors
Method to follow to to test a diode or transistor to know if they are working fine
Impedance of a capacitor – Capacitive reactance
The Impedance of a capacitor (Capacitive reactance) is the measure of the opposition to a change of the electrical current in this component.
