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)
