Total Current Formula
The following formula is used to calculate the Total Current.
IT = VT/RT
- Where IT is the Total Current (amps)
- VT is the total resistance (ohms)
- RT is the total voltage (volts)
How to Calculate Total Current?
The following two example problems outline how to calculate the Total Current.
Example Problem #1:
- First, determine the total resistance (ohms). In this example, the total resistance (ohms) is measured to be 500.
- Next, determine the total voltage (volts). For this problem, the total voltage (volts) is calculated to be 12.
- Finally, calculate the Total Current using the formula above:
IT = VT/RT
Inserting the values from above and solving the equation with the imputed values gives:
IT = 12/500 = .024 (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 resistance (ohms) = 600
total voltage (volts) = 15
Entering these values into the formula above gives :
IT = 15/600 = .025 (amps)
