A generator with an output voltage of 2 mV has a generator output resistance of 75 Ω. It drives an amplifier with an input impedance of 200 Ω. The amplifi er gain is 30, the output impedance is 300 Ω, and the amplifier load is 600 Ω. What is the output voltage?
Using 1.5v batteries, a switch, and 3 lamps, device a circuit to apply 4.5v across one lamp, two lamps in series, or three lamps in seris with a single control switch. Draw the schematic.
A 10-µF capacitor is charged to a potential of 100V. At time zero it is discharged through a 1-M ohm resistor. What is the time constant for this system
A magnetic field of 6.0 u T is to be produced 10 cm from a single long straight wire in air. How much current must it carry?
Before a program written in C can be executed on a computer, what step is required to be done first? Briefly explain this step and how it can be done effectively.
The discussion must address phase angle relationships of current and voltage. The answer must include the effect of source frequency on the voltage drolps across the resistor and the inductor at very loave and very high frequency values.
Design a non-inverting amplifier with a voltage gain of approximately 12 with an input resistance of 12kOhm. Use SPICE to confirm the result using a simple model of the OpAmp
Consider a CMOS inverter fabricated in a 0.25-μm CMOS process for which VDD = 2.5 V, Vtn-Vtp = 0.5 V, and μnCox = 3.5μpCox = 115 μA/V2. In addition, QN and QP have L = 0.25 μm, and (W/L)n = 1.5.
Three single phase transformers are used to form a three-phase transformer bank rated 13.8kV (delta)/120kV (wye). One side of the transformer bank is connected to a 120kV transmission line.
A 3-phase, 20 kVA, 208 V, 4-pole star-connected synchronous generator has a synchronous reactance of Xs = 1.5 ohm per phase. The resistance of the stator winding is negligible. The machine is connected to a 3-phase 208 V infinite bus.
The impurity is removed with practically no loss of carrier liquid. By local ordinance, a maximum of 100 ppm is allowed in the discharge to a nearby river. The treating process removes all but 10 ppm.
A silicon bar is 2 micro meters long and has 100 micro meters squared cross section. It is doped with 1x10^17 cm^3 arsenic. a) Find the current with 1V applied at room temperature b) How long does it take for an electron to drift from one end of the ..
Laplace transforms enable interpretation and manipulation of different signals by viewing these signals as either time domain signals/pulse or else frequency domain representations
