Question

Compare the potentials (V) and potential energies (U) for protons placed at points i and f. What are the magnitude and the direction of the current in the last wire? A out the junction 15 A into the junction 1 A into the junction 15 A out the junction Not enough information to determine A long conductor carrying a current runs next to a loop of wire. The current in the conductor varies as in the graph. Which segment of the graph corresponds to the largest magnetic flux in the loop? [Note that there is another similar but not identical problem on the exam] A long conductor carrying a current runs next to a loop of wire The current in the conductor varies as in the graph. Which segment of the graph corresponds to the largest induced current in the loop? (Note that there is another similar but not identical problem on the exam] All the bulbs in the circuit below are identical, and can be considered to act like perfect resistors. What happens to the potential difference across bulb A when the switch is closed? Select one: It doubles. It increases by 50% It increases by 33%. It is unchanged. E The answer depends on the value of the battery voltage In the circuit below, what is the equivalent resistance between points a and b?
