The core-loss (hysteresis + eddy-current loss) for a given specimen of magnetic material is found to be 2000 W at 50 Hz. Keeping the flux density constant, the frequency of the supply is raised to 75 Hz resulting in core-loss of 3200 W. Compute separately hysteresis and eddy-current losses at both the frequencies.
the current flowing through a circuit is it4t3a. how much charge passes through the circuit element between 0 and 2
A plane electromagnetic wave of frequency 300 MHz propagates in homogeneous sea water (ε=80,σ=1) along the z-axis. The effective field strength at the excitation point(point of origin) is 0.1V/m.
Point charge between parallel conducting planes. Consider a charge embedded in a dielectric material as shown in Figure 5.41. The dielectric is bound by two parallel plates, each held at a constant potential V0.
Design the simplest circuit that has three inputs x1,x2, x3, which produces an output value of 1whenever two or more of the input variables have the value 1;otherwise, the output has to be 0.
The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 170-F capacitor is initially charged to 100 V
what size capacitor should be placed in series with the series combination of 800 ohms and 20mH to give an admittance whose magnitude is 1m/ohm at w=10k rads/s
A collector modulated transmitter has a supply voltage of 48 V and an average collector current of 600 mA. What is the input power to the transmitter How much modulating signal power is needed to produce 100 percent modulation
The Ic was measured for different values of a load resistance. It was noticed that Ic was pretty much constant for the first 1900 ohms values, but then it suddenly decreased. Why did that happen
A p-n junction is made by doping Silicon with donors and acceptors. The doping at the p side has a uniform density of NA, but the doping density at the n side is not uniform and changes linearly with the distance from the metallurigical junction.
A 19.0 k resistor and a capacitor are connected in series and then a 16.0 V potential difference is suddenly applied across them. The potential difference across the capacitor rises to 12.00 V in 1.40 µs.
At a given instant, the total system loads are 260 MW at a frequency of 60 Hz. What are the no-load frequencies of each of the system's generators?
Calculate the frequency of the recovery voltage transient and the maximum voltage to appear across the CB contacts
