Get started for freeA power supply is connected to two bare wires that are inserted into a glass of saltwater. The resistance of the water decreases as the voltage is increased. Sketch a graph of the voltage versus the current in the water showing this type of behavior.
A student using a sensitive meter that measures resistance finds that the resistance of a thin wire is changed slightly when it is picked up with a bare hand. What causes the change in the resistance, and does it increase or decrease?
In otherwise empty space, what would happen if the size of the clectrostatic force acting between two positively charged objects was exactly the same as that of the gravitational force acting between them? What would happen if they were moved closer together or farther apart?
If the electric utility company where you live suddenly changed the frequency of the \(\mathrm{AC}\) to \(20 \mathrm{~Hz}\), what problems might this cause?
Two \(1.5\) -volt batteries are connected in series in an electric circuit. Use the concept of energy to explain why this combination is equivalent to a single 3-volt battery. When connected in parallel, what are two \(1.5\) -volt batteries equivalent to?
