An automobile battery is charged with a constant current of 2 A for five hours. The terminal voltage of the battery is v = 11 + 0.5t V for t > 0, where t is in hours. (a) Find the energy delivered to the battery during the five hours. (b) If electric energy costs 15 cents/kWh, find the cost of charging the battery for five hours.
The output of a communication channel is Y = X + N where X and N are independent, zero mean, random variables. X represents signal and N is noise. (a) Find the correlation coefficient between the input X and the output Y.
A wire with a circular cross section of radius a = 10[mm] carries a current of 10 [A]. Assuming thecurrent is uniformly distributed in the cross section, determine the volume current density.
The exciting current for a certain 50 kVA, 480-240V, 60 Hz transformer is 2.5 percent of rated current at a phase angle of 79.8 degrees. Sketch the equivelent circuit and phasor diagram for the no-load conditions and assuming operation is in the s..
suppose the conductor arrangement of a power line under planning shown below. the line will connect the hydroelectric
Build a circuit to compute the parity of an 8-bit number using NAND gates only. The parity is defined as 1 if and only if there are an odd number of 1's in the 8-bit number.
The following test data were taken on a 110-KVA, 4400/440- volt, 60-Hz transformer: Short Circuit Test: P= 2000w, I = 200 amp, V = 18v Open Circuit Test: P=1200w, I= 2 amp, V = 4400v Calculate the voltage regulation of this transformer when it suppli..
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.
use as few 3times8 binary-decimal decoders and 3-input nor gates as possible to implement a bcd squaring circuit.
A 10Ω resisitor is connected across a 120-V rms sinusoidal 60-Hz line. What value is the closest to the average current flowing in the resistor between t=0 and t=.0042 sec
In the United States, coal is a fossil fuel, used mainly to fuel the energy needed for electric power plants to manufacture electricity. The air pollution caused by burning coal has been linked to health problems and concerns for the general popul..
A 2.67-F and a 4.20-F capacitor are connected in series across a 25.0-V battery. A 8.24-F capacitor is then connected in parallel across the 2.67-F capacitor. Determine the voltage across the 8.24-F capacitor.
a) Write the real-time expressions in the z=0 plane. What kind of polarization exists here Is is clockwise or counterclockwise (looking along +z) b) Find the expression for the accompanying H(z) field.
