1) Why do we say the "voltage across" or "the voltage with respect to?" Why can't we just say voltage? a) Voltage is a measure of electric potential difference between two electrical points. b) It's an electrical cliche. c) The other point could be negative or positive.   2) If you plot voltage vs. current in a circuit, and you get a linear line, what is the significance of the slope? a) Power b) Discriminant c) Resistance   3)  Which of the following would be the resistance an ideal voltmeter, which could measure a circuit while affecting it the least? a) The same resistance as the battery b) infinity c) The same as the total equivalent resistance of the entire circuit d) zero
