3. ### If the 225 pF capacitor stores 380 pF of charge on its plates, what is the unknown capacitance? ?

charge is not in pF, it is in coulombs. Your question makes no sense. Try to restate it clearly. .

7. ### when you pay your electricity bill, do u pay for S,Q or for P?If we use PF correction can we reduce the bill?

I don't know what S Q and P are. You pay for real inphase power only, is my understanding. PF correction does not reduce the bill, but check with your power company to be sure. .
