inductive input filter if the maximum value of the load resistor is 15,000 ohms. 2. Calculate the DC base current iB of a transistor circuit if the DC collector current LC is
4.9 mA and the DC emitter current 1E is 5mA. 3. From the above transistor circuit, calculate the DC values of alpha (1 and beta [3.7 4. A FET circuit consists of a depletion MOSFET and two resistors R1 and R2. The value of
R1, the source resistor, is 55 ohms. The source to drain current is 150mA. Calculate the voltage drop across the source resistor. 5. Calculate the intrinsic standoff ratio, eta (H) of a UJT circuit where RBI is 1500 ohms
and R132 is 265 ohms. 6. What is the peak inverse voltage (PIV) across the diode during the negative half—cycle
of AC input voltaoe of 240 VRMS in a half—wave rectifier circuit? ion 7. 10. Calculate the resistance, R, of a spool of wire consisting of 500 ft of 20 gage copper
wire. The cross—sectional area of the wire is 1,022.0 circular mils and the resistivity
(p) of 10.4 ohm—mil2/1000 ft at 20°C. . In an amplifier circuit, the input power is 500 milliwatts and the output power is 3 watts. What would be the dis gain of this amplifier circuit? Vl AMPLlFIER In the circuit above using the labeled values in the figure, what would be the dB volt—
