WebJan 21, 2016 · To obtain 12V in the output the R2 will be. R2 = ( 12 x 240 / 1.25 ) – 240. R2 = 2064 ohms. Approximating this value will give 2K resistance and therefore we have fixed R2 as 2K in our schematic diagram. So using the same formula for 9, 6, 5 and 3.3v we will get resistances 1.5K , 1K , 750 and 390 ohms approximately. WebSep 21, 2010 · NiMH Battery Charger Circuit Schematic. Around 2.6 volts drop develops across the LED which appears at the base of T1. Emitter – base junction of T1 drops around 1.2 volts. So 2.6 – 1.2 volts gives 1.40 volts. So the current passing through R1 will be 1.40 V / 10 = 0.14 Amps or 140 Milli Amps. The LED act as the charging status indicator.

WebNov 5, 2013 · Let's say for sake of example you have a typical 20 mA green LED that drops 2.1 V. The battery puts out 9 V, so that leaves 9V - 2.1V = 6.9V accross the resistor in series with the LED. These LEDs can take 20 mA of current, but unless you expect to use it in a bright environment that will be overkill. Let's aim for about 10 mA LED current.
