You want to use two light bulbs to light a room but only have one battery to power them. The greatest possible light will be produced by hooking them up: A. in parallel B. in series  is it A or B?

The Voltage V in volts , the resistance R in ohms , and the current I in amperes in an electric circuit are related by the formula V = R I. The resistance in an electrical circuit is decreasing at the rate of 4 ohms / s, while the voltage remains constant at 12 volts. At what rate is the current changing at the instant the current is 6 amperes? The current is decreasing at the rate of 12 amperes / s The current is decreasing at the rate of 18 amperes / s The current is increasing at the rate of 18 amperes / s The current is increasing at the rate of 12 amperes / s The current is decreasing at the rate of 3 amperes / s O The current is increasing at the rate of 3 amperes / s

Problem 4: The charge on a capacitor in a circuit is given by q(t) = qmax cos(wt + q) Enter an expression for the current flowing into the capacitor as a function of time. I(t) = 1
