How transistors work Gokul J. Krishnan TED-Ed

A transistor can conceptually open or close electric circuits by altering the emitter collector resistance from it's minimum value ("close") to it's maximum value ("open") or vice versa. Turning "off" The electric curcuit attached to the emitter collector line of a bipolar junction transistor is "open", if 0V are attached to it's base pin. The most simple circuit consists of a transistor and a

When the switch is open no base current flows, so the transistor switches off the collector current. Both LEDs are off. Both LEDs are off. You can build this circuit with two standard 5mm red LEDs and any general purpose low power NPN transistor (BC108, BC182 or BC548 for example).

Laser ON/OFF switch using NPN transistor CircuitLab

This hybrid circuit uses a mixture of transistors, an IC and a relay and is used to automatically open or close a pair of curtains. Using switch S3 also allows manual control, allowing for curtains to be left only partially open or closed. The circuit controls a motor which is attached to a simple pulley mechanism, to move the curtains. I first started this circuit over 20 years ago and apart

Transistor closes when current is applied how to make it

5/10/2009 · A transistor is like a switch, there is an in, out, and a control. When current flows to the control, then the transistor turns on like a switch allowing current to flow through the in and out and that is considered to be on.

How to test a transistor with DMM? androiderode.com

When the base of the transistor is not supplied with input , it acts as open switch. In npn transistor, the middle region (base) is positive . So if negative input is given, it makes the transistor act as open switch. In case of pnp transistor, positive input will make it open circuit for similar reasons. In this way, a transistor can be made to act as an open switch which can be closed by

Laser ON/OFF switch using NPN transistor CircuitLab

This project shows how to assemble a simple transistor NOT gate on a solderless breadboard. For this electronics project, a normally open pushbutton is used as the input. When the button isn’t pressed, the input is LOW and the output is HIGH, which causes the LED to light. When you press the button, the input goes HIGH, the output goes LOW, and the LED goes out.
