A P=900W electric motor with pf=0.82 lagging is connected to a 240 Vrms 60 hertz source. a) Draw an equivalent circuit showing impedance and phasor values for Vs, R and X. b) Find an Xc value to put in parallel with the motor which corrects the pf to..
For an armature-control DC motor the following parameters are given: ea=22V, f=5x10^-3 onz-in/rad/sec, J=4.27X10^-4 in-onz-sec^2, La=0, Ts=10 onz-in (stall torque), wo= 480 rad/sec (no load speed), K=7.66 in-onz/amp.
A mealy sequential circuit has one input (x) and one output (z). Z = 1 if and only if the most recent input, combined with the preceding 3 inputs, was not a valid BCD encoding of a decimal digit; otherwise, z = 0.
Determine: (a) the resistance of the coil,(b) the current flowing in the circuit one second after the shorting link has been placed in the circuit, and (c) the time taken for the current to fall to 10% of its initial value.
The design of the amplifier shall be performed for the Fairchild Q2N3904 NPN Transistor. Specifications can be obtained from the datasheet for the Fairchild Q2N3904 and are typically given in a variety of ways. Minimum and maximum operating condition..
The ALU required for this lab accepts two 4-bit inputs (A0 - A3, B0 - B3), a 3-bit function selection code (F0 - F2) and outputs a 5-bit result (S0 - S4). Since the function selection uses 3-bits, there are 8 different functions.
How much work is required to move a charge of 0.02 microcoulombs from one point to another if the potential difference between the points is 6.3 volts
The plates of a parallel-plate capacitor have areas of 40cm2 and are separated by 0.2mm of waxed paper (K=2.2). Find its capacitance.
