AC generator and DC generator.

Differentiate between AC and DC by giving two points .

An dielectric current has both DC and AC components . DC component of BA and AC component is given as I = 6sin omega t. So underset(rms)(I) value of resulatant current is

Incorrect statement are :- (a) A.C. meters can measure D.C also (b) If A.C. meter measures D.C. there scale must be linear and uniform (c) A.C. and D.C. meters are based on heating effect of current (d) A.C. meter reads rms value of current

How is AC different from DC?

To express AC power in the same from as DC power, a special value of current is defined and used, is called

In DeltaABC , if AB=AC and BD=DC (see figure), then angleADC=

Inductance of a coil is 5 mH is connected to AC source of 220 V, 50 Hz. The ratio of AC to DC resistance of the coil is

In a ? ABCD , AB | | DC. P and Q are the mid-points of AB and DC respectively AC, BD meet at O.Show that P , O , Q are collinear.
