Let's determine the relationship between voltage and energy.
Voltage can be said to be the work done in moving a unit positive charge from one point to another against the electric field.
It is used to measure electric potential which is a form of potential energy.
Energy can be said to be the integral of power over time. It is the potential to do work.
The expression to find energy is:
Energy = Power x Time
Volt is the per unit charge while energy is the volts times charge.
We have the formula:
Where:
• V is the voltage
,
• W is the energy
,
• Q is the charge.
Therefore, the relationship between voltage and energy is that voltage is the energy per unit charge at some point in space.
ANSWER:
c. Voltage is the energy per unit charge at some point in space.
