HOW TO CALCULATE THE VALUE OF RESISTOR FOR LED CIRCUIT

Different color light emitting diode LED

A light emitting diode (LED) circuit in electronics is an electrical circuit that powers an LED. The circuit must limit the current to avoid damaging the LED while supplying enough current to illuminate the LED at the necessary brightness. The…

VOLTAGE DIVIDER CALCULATION

Through hole resistors with long leads

A voltage divider is a passive linear circuit that produces an output voltage that is a fraction of its input voltage. The most common voltage divider is two resistors connected in series, with the input voltage applied across them and…
