Answer the following question given this paragraph: The second equation is equivalent to the first. Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since PE = qV . The car battery can move more charge than the motorcycle battery, although both are 12 V batteries. Q: What term is not the same as energy, but means the energy per unit charge? Choices: - frequency - speed - mass - voltage A:
voltage
