A single phase bridge rectifier is supplied from a 60 Hz sinusoidal source of magnitude Vm = 120V. The land is a resistance of value R=5000. The output RMS current expression is given below. The value of the inductance that should limit the RMS current IC to less than 5% of loc would be equal to: Select one: 2.22 A three phase bridge rectifier has a purely resistive load. The rectifier delivers 45 A current at an average output voltage of Vdc = 300 V. The rms output voltage Vrms is equal to: Select one: 240 150 L300.25V c80V Od 27.5V A transistor is used as a switch. Assuming that the total power loss in the transistor (Collector and Base losses) is equal to 200 W. If the ambient temperature is 23.C, and the thermal resistors are given as RC = 0.5 C/W RCS = 0.1 C/W. RSA = 0.6 C/W, then the junction temperature Ts would be equal to: Select one: 363.0 2030 Od 2001
