Can potential difference between the terminals of a battery ever be opposite in direction to the emf? If it can, give an example. If it cannot, explain why not.
A 1500-W electric heater is plugged into the outlet of a 120-V circuit that has a 20-A circuit breaker. You plug an electric hair dryer into the same outlet. The hair dryer has power settings of 600 W, 900 W, 1200 W, and 1500 W. You start with the hair dryer on the 600-W setting and increase the power setting until the circuit breaker trips. What power setting caused the breaker to trip?
Two copper wires with different diameter are joined end to end. If a current flow in the wire combination, what happens to electrons when they move from the large diameter wire into the smaller diameter wire? Does their drift speed increase, decrease, or stay the same? If the drift speed change, what is the role the force that causes the change? Explain your reasoning.
You want to produce three 1.00-mm-diameter cylindrical wires,
each with a resistance of 1.00 Ω at room temperature. One wire is gold, one
is copper, and one is aluminum. Refer to Table 25.1 for the resistivity
values. (a) What will be the length of each wire? (b) Gold has a density of.
What will be the mass of the gold wire? If you consider the current price of gold, is
this wire very expensive?
