The insulation resistance of a kilometer of the cablehaving a diameter of 2 cm and an insulation thickness of 2 cm is600 ohms. if the thickness of the insulation is increased to 3 cm,find the insulation resistance of the cable.
As far as a direct compaison of mechanical switches vs. transistors used as switches, the transistor does have a measurable impedance when ON, and a mechanical switch does not.
a) If accA holds $16 and accB holds $2A, what values will be in the each accumulators after executing the ABA instruction b) What series of instructions would achieve the 16-bit subtraction of $1234 from $8ABC
The number of turns in the primary and secondary windings of a transformer are 80 and 20 respectively. The reluctance of the core is 64x10^3 A/Wb . The primary is connected to a voltage source, Vpri(t) = 170 sin (377t) V
Generate an analogous diagram for a closed-loop controlsystem to maintain the water level in a tank that has a singleinlet valve (that can be controlled )and an unknown leak. Anexample of a closed -loop system such as this is the tank on a toilet.
A 150-MVA 15/200-kV single-phase power transformer has a 0.018ohm resistance and a 0.075ohm reactance. The magnetizing impedance is j80 per unit. a.) Find the equivalent circuit referred to the low-voltage side of this transformer.
Given the electric field of a 200 MHz uniform plane wave propagating in the z^ direction, where E is parallel to the y axis and reaches a peak value of 150 (mV/m) at t = 0 (s) and z = 0.5 (m).
Design a circuit for control of lights. There are 3 inputs:Reset, start and clock. Three outputs: Red, Yellow, Green, whichare used to turn on the lights. Only one light can be on at anytime. Reset forces the circuit into a state in which the red ..
A PMOS transistor has Vtp = -0.5V. As the gate voltage vG is varied from +2.5V to 0V, the transistor moves through all of its three possible modes of operation. Specify the value of vG at which the device changes modes of operation.
Any causal signal x(t) having a Laplace transform with poles in the open-left s-plane (i.e., not including the jΩ axis) has, as we saw before, a region of convergence that includes the jΩ axis, and as such its Fourier transform can be found from i..
The flip-flop input excitation equations are as follows: JA=XQ'B; KA=X'; JB=XQA; KB=X'Q'A The output equation: Z=XQAQB 1. Draw the circuit diagram 2. Obtain and simplify the flip-flop characteristic equations 3. Obtain the state table
3-singlephase 2 winding transformers, each rated 500 MVA, 13.8/199.2 kV, with leakage reactance Xeq = 0.10 per unit, are connected to form a three-phase bank. Winding resistances and exciting current are neglected.
In an electroplating process, copper (ionic charge +2e, atomic weight 63.6 g/mol) is deposited using a current of 10.0 A. What mass of copper is deposited in 10.0 minutes. Avogadro's number is 6.022 × 1023 molecules/mol and e = 1.60 × 10-19 C.
