A circular disk of radius a is uniformly charged over its surface by a charge of density . The disk uniformly rotates in air about its axis (perpendicular to the disk) with an angular velocity . Find the magnetic flux density vector at an arbitrary point along the axis of rotation. Assume that the charge distribution over the disk remains the same during the rotation.
a voltage divider is required to produce a 5.5V output from a 12V source. if one of the resistor values is 1.0k, what value is required for the second resistor so that the voltage across the 1.0k resistor is 5.5V
A 150-kVA, 2400/240-V single-phase transformer has the following parameters: R1 = 0.2 ; X1 = 0.45 ;R2 = 0.02; X2 = 0.0045 ;Rc = 1000 ; Xm = 1500. The transformer is connected to a 150kVA load with 0.8 power factor lagging.
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.

A part hollow non conducting sphere has a uniform volume charge density of 200 nC/m2. Find the potential difference between the inner surface at r=2cm and outer surface at r=5cm
Important information about Electrical Networks, Engine consumes 5kw of power and a reactive power of 2kvar at current of (3+j2) Amps.
The average power is not necessarily equal to the average current times the average voltage. To show this, find a voltage waveform and current waveform where each has a zero average value but their product has a non-zero value.
An induction motor has an output or shaft power of 30 kW at 86% efficiency. For this operatingcondition, stator copper loss = rotor copper loss = core loss = mechanical rotational losses. Determine the slip.
a certain ideal voltage generator is characterized as v(t) = 40 sin 377 t . If this generator is measured with a DC voltmeter, the instrument reads 12 volts, what is the rms value of this voltage waveform
