Jonathan models two kinds of circuits containing identical bulbs and batteries. If one of the bulbs in each circuit breaks, which of the following explains what would happen to the rest of the bulbs?

Electrons would stop flowing in all bulbs of circuits A and B.

The flow of electrons would stop in all bulbs of circuit A but not of circuit B.

The flow of electrons would stop in all bulbs of circuit B but not of circuit A.

Electrons would stop flowing only in the broken bulbs of circuits A and B.

Which describes the flow of current in the series circuit shown?

A. The current flows from the negative terminal of the battery, through both light bulbs at the same time, and back to the positive terminal of the battery.

B. The current flows from the positive terminal of the battery, through both light bulbs at the same time, and back to the negative terminal of the battery.

C. The current flows from the negative terminal of the battery, through the first light bulb, then through the second light bulb, and back to the positive terminal of the battery.

D. The current flows from the positive terminal of the battery, through the first light bulb, then through the second light bulb, and back to the negative terminal of the battery.

Mary wants to investigate the relationship between magnetism and the movement of an electrical charge. She has a coil of wire hooked to an ammeter to measure current. She has a moveable magnet inside the coil. As she moves the magnet within the coil, the ammeter indicates a certain current. Mary wants to increase the amount of current from the device. Which action would be the BEST to increase the current and why?

A. Use a differently shaped magnet, because it would increase the magnetic field.

B. Increase the diameter of coil, because more of the magnetic field will be included.

C. Reduce the number of coils because this would increase the effect of the magnetic field.

D. Move the magnet faster within the coil, because this will increase the rate of change of the magnetic field.
