Enter the total voltage (volts), the total current (amps), and the total time (seconds) into the calculator to determine the Energy from Voltage. 

Energy from Voltage Formula

The following equation is used to calculate the Energy from Voltage.

Ev = V* I * T

  • Where Ev is the Energy from Voltage (Joules)
  • V is the total voltage (volts) 
  • I is the total current (amps) 
  • T is the total time (seconds) 

How to Calculate Energy from Voltage?

The following example problems outline the steps and information needed to calculate the Energy from Voltage.

Example Problem #1

  1. First, determine the total voltage (volts). In this example, the total voltage (volts) is determined to be 30 .
  2. Next, determine the total current (amps). For this problem, the total current (amps) is measured to be 4 .
  3. Next, determine the total time (seconds). In this case, the total time (seconds) is found to be 2.
  4. Finally, calculate the Energy from Voltage using the formula above: 

Ev = V* I * T

Inserting the values from above and solving the equation yields: 

Ev = 30* 4 * 2 = 240 (Joules)


Example Problem #2

Using the same method as above, first, we need to measure or determine the variables required by the equation. For this example problem, these are provided as follows: 

total voltage (volts) = 2

total current (amps) = 40

total time (seconds) = 4

Enter these given values into the calculator or above yields: 

Ev = 2* 40 * 4 = 160 (Joules)
