Answer Posted / shibuss
both losses are occurred in ac
If the primary of a transformer is energized it create a
magmatic flux which linked with secondary and the core. This
flux will induce an EMF in the secondary winding and also in
the core. Since the core of the transformer forms a closed
circuit this EMF will cause a current to flow through the
core known as eddy current and hence the eddy current loss.
In ac system direction of the current is reversed in every
half cycle this will cause the magnetization of the core to
reverse in each half cycle and the loss due to this
continuous magnetic reversal termed as hysteresis loss

How to calculate VCB rating for 33KV ,25 MW Power line?
1- XC and the RC time constant are both measures of the reaction of C to a change in ____? 2-The power factor is a numerical ratio with a value between 0 and 1 equal to the ______________ of the phase angle. 3-When V and I are out of phase because of reactance, the product of V times I is called ______________ power 4-For _____________ inductors, the branch currents can be added algebraically. 5- The ______________ power in watts can be calculated as I^2R 6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL 2*3.141592653*1kHz*30mH =188 ohms Please check) 7-A parallel RL circuit has the values, R = 5kohms, XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
