Ohm's Law

[IDG-01-001]

Ohm’s Law is a formula that was first published in 1827, and was derived from the observations of the relationship between voltage, current and resistance that was made by Georg Ohm. Ohm’s Law is used in the design of electrical circuits; the troubleshooting of electrical circuits using measurements compared to known values; and calculating the proper battery and power supply sizing. Ohm’s Law applies to any device, equipment, or component that is electrical in nature. Knowledge and practical application of Ohm’s Law is a skill that will enhance electrical competence.
