Which describes the difference between the light bulbs in the series circuit and the light bulbs in the parallel circuit?

• All of the light bulbs are equally bright in both series circuits and parallel circuits.

• In the parallel circuit all of the bulbs are equally bright and in the series circuit the brightness decreases as the current flows through each bulb.

• In the series circuit all of the bulbs are equally bright and in the parallel circuit the brightness decreases as the current flows through each bulb.

• In series circuits the brightness of each bulb decreases as the current flows through each bulb and in parallel circuits the brightness of each bulb decreases as they are placed further from 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?

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

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

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

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