Inductor
Inductors are electronic components that store energy in the form of a magnetic field. They are used in a wide range of applications, from simple circuits to power supplies and filters. Understanding the principles of inductors is essential for designing and analyzing electronic circuits. Inductance is the property of an inductor that opposes any change…

Custom Aluminum Heatsink for Raspberry Pi
Raspberry Pi is good a single-board Linux based computer system. But it runs OK for the most part and does not heat up if you’re not doing CPU hogging tasks. I use my raspberry pi for watching videos. Which heats up the CPU to about 60 degrees celsius. In Delhi, in the summer the ambient…

15V Unregulated DC Power Supply using 12Vrms step-down transformer
There are two ways to make DC power supply Linear Switching Linear Power SupplyContinous control of voltage is done at any instance of time. It uses a pass transistor with an error amplifier to regulate the voltage supply.example: 7805, 7905, LM317 etc Switching Power SupplyIt also uses the pass transistor along with an inductor and…

Capacitor Time Constant=RC or Charging Time
In this video, the time constant for the capacitor is calculated. Time Constant is denoted by the symbol tau τ τ = R*C Where R = value of the resistor and C = value of capacitor

Capacitor ESR
A real capacitor has a series resistance which is due to the imperfect manufacturing process and also because of the cost regulations. lower ESR = Better Capcitor = Higher Cost A lower ESR capacitor is better but the manufacturing cost will also be on the higher side. So, there is a compromise made between ESR…

How to calculate the value of a resistor from colour codes
To calculate the value of a resistor from colour codes. Then, First, you have to locate the Tolerance band.The tolerance band mostly in most of the resistors is made from either gold colour or silver colour. Then you need to look at the next band which tells you the multiplier. Then you need to look…

Resistor
A resistor is an electronic component that offers resistance in the flow of current. The practical resistor has a slight shift in its values from the ideal counterparts. Not all the values of the resistor are available in the market. There is a certain number that is chosen and is readily available. If a particular…
