9VDC Power Supply using Zener diode and Transistor
This Power source can be used to power circuits or electronic devices that would normally use a 9 volt battery, saving us the cost of the battery while being used at home.
How to Measure Beta of a Transistor? (β / hfe of transistor)
The beta (β) is a characteristic of each transistor. This feature is found in the NTE, ECG manuals, etc. These manuals have a minimum or approximate values of the real values. This means that we do not know the real value of the transistor.
Transistorized Voltage Regulator Why use a transistorized voltage regulator? If we use a half or a full-wave rectifier we can convert an AC voltage in a DC one. This converted voltage is unregulated, because the output voltage is not constant and can change due to variations of the load value. To reduce these variations we connect […]
