We are given four resistors with resistances 1, 2, 3, and 4 Ω (a) If they are connected together in series to a 11-volt battery, what is the total resistance and how much power is consumed? (b) If they are connected together in parallel to a 11-volt battery, what is the total resistance and how much power is consumed?

You can watch static electricity in action by rubbing an inflated balloon against your hair. your hair will actually stand on its end! it does this because each hair becomes charged, and they all repel one another.
