## Current Formula

The following formula is used to calculate the Current.

**I = V/R**

- Where I is the Current (amps)
- V is the total voltage (volts)
- R is the total resistance (ohms)

## How to Calculate Current?

The following two example problems outline how to calculate the Current.

**Example Problem #1:**

- First, determine the total voltage (volts). In this example, the total voltage (volts) is measured to be 100.
- Next, determine the total resistance (ohms). For this problem, the total resistance (ohms) is calculated to be 25.
- Finally, calculate the Current using the formula above:

I = V/R

Inserting the values from above and solving the equation with the imputed values gives:

I = 100/25 = 4 (amps)

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

total voltage (volts) = 200

total resistance (ohms) = 50

Entering these values into the formula above gives :

I = 200/50 = 4 (amps)
