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

Energy from Current Formula

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

E = I * V* T
  • Where E is the Energy from Current (Joules)
  • I is the current (amps) 
  • V is the voltage (volts) 
  • T is the time (seconds) 

To calculate the energy from the current, multiply the amperage by the voltage and time.

How to Calculate Energy from Current?

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

Example Problem #1

  1. First, determine the current (amps). In this example, the current (amps) is determined to be 4 .
  2. Next, determine the voltage (volts). For this problem, the voltage (volts) is measured to be 3 .
  3. Next, determine the time (seconds). In this case, the time (seconds) is found to be 10.
  4. Finally, calculate the Energy from Current using the formula above: 

E = I * V* T

Inserting the values from above and solving the equation yields: 

E = 4*3*10 = 120 (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: 

current (amps) = 50

voltage (volts) = 4

time (seconds) = 2

Enter these given values into the calculator or above yields: 

E =50 * 4* 2 = 400 (Joules)
