And, if we talk about switching, there are two types of transistors NPN and PNP. In this tutorial we will show you how to use a NPN and PNP transistor for switching, with example transistor switching ...

So here we are building the simplest circuit in Electronics which is Glowing the LED using a Resistor and Battery. This is the first basic LED circuit I built many years ago in my school days and had ...

With reference to Figure A., when the main supply is applied to the circuit the 220-µF capacitor, C1, charges quickly to +6 volts through resistor R3. The circuit is now awaiting voltage on the ...

Here the first gate (N1) is designed as a simple oscillator with resistor R1 and capacitor C2. The remaining gates are used as inverters and buffers. The output of gate N1 (pin 3) is fed to gate N2 ...

Another “learning tool” is a basic, all-analog Lightning Detector circuit (not, you don't use it by setting it up at spots it will likely strike ground, so there's no danger). Nothing is critical ...

This paper discusses a generalized resistor-transistor logic circuit; i.e., the output produces a signal when any m out of the n inputs are ``on.'' Practical limitations such as using precision power ...

Here is a simple circuit diagram of 88-108 MHz FM Radio Receiver Circuit diagram. The circuit is very simple and the components used in this circuit can be easily available in a market and also the ...
