Ohm's Law

Resources : Ohm's Law

A. When Volts and OHMS are known:

Example: Find the current of a 120 volt circuit with a resistance of 60 OHMS.

B. When Watts and Volts are known:

Example: A 120 Volt Circuit has a 1440 Watt Load. Determine the current.

C. When OHMS and Watts are known:

Example: A circuit consumes 625 watts through a 12.75 OHM resistor. Determine the current.

Notes:

  1. One Electrical Horsepower = 746 watts. Electric Motors are rated in horsepower.
  2. One kilowatt = 1000 watts. Generators are rated in kilowatts.
