WebbI = 44V x 5.4 = 8.15A. So the dissipated peak power on the resistor would be P = 44V / 2 * 8.15 = 180W Having 400uF load capacitance, the pulse duration would be about t = 5 * R *C = 5 * 5.4 Ohm * 400uF = 10ms So I would need a 2.7 Ohm resistor with a maximum pulse dissipation of 180W for 10ms. Webb4 apr. 2016 · Does a diode require a protective resistor is it has a varaible resistor in front of it. The question is to create a circuit diagram to obtain the IV curve for a semi-conductor diode. I put a cell, an ammeter, a diode in forward bias (with a voltmeter in parallel) then AFTER the diode I put a Rheostat to adjust the resistance. mavericks vs grizzlies prediction

Current Limiting Resistor: Protective Resistor for Regulating Current

Webb8 dec. 2024 · 1 When one needs to protect a transistor or I/O pin of a processor, then a TVS diode can be placed between the connector and the transistor. Also a series resistor (R1) can be placed between the connector and the TVS diode in order to protect the diode. However, is it useful to have a resistor (2) between the diode and the transistor?
