How does a capacitor improve power factor?
How does a capacitor improve power factor?
Last answer:
Every circuit are usually more inductive than capacitive.it means that the current lags by voltage at small angle.hence we have to compensate this situation so we use Capacitor then this lag is compensate ... angle becomes low and the value of cos(phase angle) is increase and hence power also max.

Why can't we store AC in batteries instead of DC ?
Why can't we store AC in batteries instead of DC ?
Last answer:
Because the direction of the current changes in AC electricity, you cannot directly store the power. Placing a capacitor in an AC circuit has no effect on the alternating flow of the electricity. The only ... is indirectly, by storing DC and then using a power inverter to convert the DC to AC.
