Enter the total voltage (volts) and the total resistance (ohms) into the calculator to determine the Current.

## 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:

1. First, determine the total voltage (volts). In this example, the total voltage (volts) is measured to be 100.
2. Next, determine the total resistance (ohms). For this problem, the total resistance (ohms) is calculated to be 25.
3. 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)
