WebDec 10, 2016 · For example, put three of your IR LEDs in series, and calculate R so that 1.2 V drops across a resistor and 3.6 across the series of LEDs. Also try four LEDs in series, and calculate R to drop 0.1 to 0.3 V. Edit 1: Ignacio Vazquez-Abrams says, a little obscurely, “Getting warmer. WebThis is LCR-T4 12864 LCD Graphical Transistor Tester Resistance Capacitance ESR SCR Meter. It is powered by 9V layer-built battery or can use 2 li-ion batteries to form an 8.4V battery pack for long time power. This tester can be used to measure bipolar transistor current amplification factor and base-emitter threshold voltage.
