Question

Which of these statements is true about a battery? O It accumulates like charges all at the same point for a long time. O It prevents electric charges from flowing out of its terminals. O It pushes electrons out of its terminals in alternating directions. O It keeps a constant potential difference between two points. O It produces a constant electric current between any two points. What is the meaning of Ohm's law for conductors? O O O The resistance between two points is proportional to the applied voltage. The voltage between two points is always independent of the current. The ratio of the applied voltage over the observed current is constant. If something could go wrong in a conductor, it usually will go wrong. The resistance between two points is proportional to the observed current. O

Explanation / Answer

1. It keeps a constant potential difference between two points.

2. The ratio of the applied voltage over the observed current is constant.
