Small switches called transistors are found in almost every electronic device. However they are unable to manage an abundance of power alone. A transistor relay driver is similar to a specialized transistor adapter. It enables the control of a strong relay switch by a tiny transistor signal. This makes it possible to turn ON and […]

Simple Current Limiter Circuit using Transistors
Designing a circuit that limits the amount of power that is supplied to other electronics is addressed in this tutorial. Working as a protection to avoid overload it makes use of two transistors and a particular resistor. What is a Current Limiter Circuit using Transistors: The current flowing through a load is limited by a […]
Simple Voltage Regulator Circuit using Transistor and Zener
This circuit is like a bouncer for electricity. It uses a transistor like a gatekeeper and a special Zener diode to make sure the voltage stays steady. The Zener diode is like a set point and the transistor copies that voltage keeping it constant for ones electronic devices. This is a great project where ups […]
