NPN Transistor Switching Circuit Diagram . Now as you see in the circuit diagram below, we made a voltage divider circuit using LDR and 1 mega ohm resistor. When there is light near the LDR, its ...

This is the first basic LED circuit I built many years ago in my school days and had given me immense pleasure to see glowing LED. For building this circuit you only need four things: LED- 1; Resistor ...

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 ...

Easy Transistor Tester. The circuit employs the properties of the gates of low power IC 4093. It is a NAND IC with four gates that can be designed in various ways. Here the first gate (N1) is designed ...

To do this, you have to anticipate shortcomings and then provide enhancements which overcome them. You also have to do basic real-world analysis, such as the power dissipation of the transistor if the ...

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 ...

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 ...
