23) One advantage to this form of circuit is that voltage available to each light remains constant regardless of the A) number of lights that are on. current drawn from the battery remains constant regardless of the B) number of lights that are on. resistance along the circuit remains constant regardless of the C) number of lights that are on. current drawn from the battery decreases as more D) lights are turned on. None of the E) above Explanation: Unlike a series circuit, this type of circuit allows current and resistance to act independently for each loop so that voltage available to each light remains constant regardless of the number of lights that are on. 24) Turning a magnet very quickly would be BEST used to create A) radiation. B) waves. an electric C) current. a convection D) current. None of the E) Explanation: The reason that electric motors have magnets inside them is because they are essentially generators in reverse. They use electricity to turn a magnet, which then produces useful motion. A turning magnet will produce an electric current if placed near wires. 25) Which graph BEST represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator? A) B) C) D) None of the E) above Explanation: As an electrical generator spins faster, it creates more current as is shown by graph B. 26) During induction, a positively charged rod is brought near to but not touching the electroscope. The presence of the charged object above the plate of the electroscope induces charges to move down into the gold leaves, giving the
