four loads are connected in series across 110 volts D.C.THE loads fail to operate.a voltmeter connected in succession across each device reads 0 across the first three loads and 110 volts across the fourth load.What circuit fault is indicated at the fourth load?
1)Convert the binary number (0.1000)2 to decimal. 2)The number (17)10 represented as an unsigned, 6-bit binary number is 3)The number (-25)10 in 6-bit sign magnitude format is 4)The number (32)10 in 6-bit 2's complement is
A 480 V permanent magnet ac motor is consuming 10 kW at power factor 0.80 lagging. Its speed is 1800 rpm. The winding resistance is 0.5 ohms per phase. Core losses are 100 W. Mechanical losses are 250 W. Stray losses are 1.5% of the input power
A four DC shunt generator has Φ=.06 Wb/pole, Z=175, n=1800 rpm, coverage, PFC= 0.8 A. Calculate the generated voltage B. If the load voltage is 240 V and the full load current is 100A, Calculate the armature resistance.
The junction capacitance Cj of a one-sided silicon pn junction (i.e. one side of the junction is highly doped, the other side is much lower doped, e.g. n+p or p+n) at T = 300 K is measured under a reverse bias VA = - 50 mV and found to be 1.3 pF.
A large brass washer has a 2 cm inside diameter, a 5 cm outside diameter, and is 0.5 cm thick. Its conductivity is s=1.5 X 107 S/m. The washer is cut in half along a diameter, and a voltage is applied between the two rectangular faces of one part.
How many turns of wire are required to produce a B-field whosemagnitude is greater than or equal to 10-3[T] inside anair-wound solenoid that is 2 [cm] long and carries a current of 100[mA].
A meter being used for a 2-wire resistance measurement has an internal current source of 1 mA. If the meter's test leads have equal resistances of 0.06-ohm, what is the measured resistance for: A resistor of actual value 0.5-ohm
When the scope probe is properly calibrated, it can be modeled as a 9[M Ohm] resistor in parallel with a capacitor having a capacitance l/9th that of the oscilloscope input capacitance.
Design the datapath which will add the value in register A to the value in either of the registers B or C and store the value back in A. The input to the datapath should be a control signal s: if s = 1 then A + B should be calculated; If s = 0 the..
