## 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**

- First, determine the total voltage (volts). In this example, the total voltage (volts) is determined to be 30 .
- Next, determine the total current (amps). For this problem, the total current (amps) is measured to be 4 .
- Next, determine the total time (seconds). In this case, the total time (seconds) is found to be 2.
- 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)
