120 |
= 12 Amperes |
C. When OHMS and Watts are known:
Example: A circuit consumes 625
watts through
a 12.75 OHM resistor. Determine the current.
Notes:
A. One Electrical Horsepower = 746 watts. Electric Motors are rated in
horsepower.
B. One kilowatt = 1000 watts. Generators are rated in kilowatts.
