Q. A balanced three-phase, wye-connected, 2400- V, 60-Hz source supplies two balanced wye- connected loads in parallel. The first draws 15 kVA at 0.8 power factor lagging, and the second needs 20 kW at 0.9 power factor leading. Compute the following:
(a) Current supplied by the source.
(b) Total real and reactive power drawn by the combined load.
(c) Overall power factor.
If a current of 10A flows for four minutes, find the quantity of electricity transferred. Quantity of electricity, Q=It coulombs. I =10A and t = 4 × 60 = 240s. Hence Q =
what is force?
Suppose the ambiguity function of some waveform x ( t ) of duration ζ = 1 millisecond is given by (NOTE: this is not a possible AF because it is not time-limited to
Q. Determine the voltages V x using voltage division and equivalent resistor reductions for the circuits shown in Figure.

The Octal Inverter 74LS 240 It is similar to above octal buffer but with inverter output. The logic diagram is shown in figure below . Normal 0
Use basic circuit theory to convert the "T" circuit below into the equivalent "π". Hint: Remember to disconnect the voltage source and the load.
With the help of energy bands explain how conduction takes place in insulators. Insulators: Substance as wood, glass, that do not permit the passage of current through them
