Which of the following creates a voltage difference?
a. battery
b. amperes
c. charge
d. resistance

The correct option is C

Explanation:

A battery is an electrochemical device that converts chemical energy into electrical energy. Electrochemical device contains two electrodes (anode and cathode). These two electrodes are placed in contact with an electrolyte. A spontaneous chemical reaction (redox reaction) causes electrical energy/current to be produced. This chemical reaction causes a potential difference (which produces electric current/charge). However, this charge/electric current causes a voltage difference.
