Light Emitting Diode Part IVTHE RESISTOR
The value of the current limiting resistor can be worked out by Ohms Law.
Here are the 3 steps:
1. Add up the voltages of all the LEDs in a string. e.g: 2.1v + 2 ... readmore
LED LampsLED LampsBeing solid state devices, Light Emitting Diode (LED) Lamps have inherent characteristics assuring high reliability and a compatibility with low current electronic drive circuits.
LEDs have ... readmore
Bridge rectifiersThere are several ways of connecting diodes to make a rectifier to convert AC to DC. The bridge rectifier is one of them and it is available in special packages containing the four diodes required. B ... readmore
Voltage Follower Circuit
Two examples of the most common types of Voltage followers (buffers). You can find some theory behind them in our amplifier gain and buffer amplifier pages.
Transistor voltage follower:
