Three Phase Formula
Today we are sharing a super quick tip with you. The biggest error that most test takers make is when calculating a three phase formula. A three phase system must have the voltage multiplied times a factor of 1.73. (Or the square root of 3.) Without getting into heavy math or complex electrical theory; three-phase voltages must be multiplied by 1.73 at all times.
We hope this helps get you started. If you are truly serious and intent on passing the electrical license exam, register for the 2-day crash course today and get that license in your pocket. Remember, your license application expires after 12 months. Get it done!
Prepare. Pass. Excel.
