Explain the relationship between voltage and electrical energy.

Voltage is directly related to the potential energy in a system. They are not the same thing, but the voltage is a measure of the energy per unit charge.

How can you calculate the energy delivered by a battery?

The energy delivered by a battery can be calculated by multiplying the voltage of the battery by the total charge it delivers.

What is the main difference between voltage and energy in the context of electricity?

Voltage is a measure of energy per unit charge, while energy is the total amount of stored energy in a system.

Provide an example that illustrates the difference between voltage and energy.

A motorcycle battery and a car battery can have the same voltage, but the car battery stores much more energy due to its larger size. Signup and view all the answers
