Answer / shakeel tu

it is the cosine of the angle between voltage and
current.so we can write vi sin(some angle).

Answer / balaji

The real power means p=visin
angle,The reactive power means p=vicos angle...
the ex for reactive power is battery...in a power station
the reactive power is used to inject in the some additional
to real power.....

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.

There are 2 Flip_Flop with logic between them. Given Clock to Q delay, logic prop. delay, set up and hold times specify maximum clock frequency of system. What happens if second output fed back to first input. Any changes? What happens with timing if second output is fed back to logic between the flops? Good Luck!
