For the circuit of Figure, given that VCC = 5V, RC = 1k, β = 100, and the high range is 4 to 5 V, choose RB such that any high input will saturate the transistor with the base overdriven by a factor of at least 5. Assume Vsat to be 0.2 V.
Verify the minimum & maximum load current for which the zener diode will keep regulation. Find the minimum value of RL that can be used. The zener diode has V Z = 12V, I ZK =
When delivering rated load a 10-kW, 230-V self excited shunt generator has an armature-circuit voltage drop that is 6% of the terminal voltage and a shunt-field current equal to 4%
