Use of Ohm's and Kirchhoff's Laws in DC Circuits

SKU: ELOHKI0CENDuration: 60 Minutes

The relationship between current, voltage, and resistance was described by George Simon Ohm in a form that commonly is referred to as Ohm's law. Ohm's law states that current is equal to voltage divided by resistance. This law is often expressed using symbols for each quantity. The letter I is used to represent current, E represents voltage, and R represents resistance. Using these symbols, Ohm's law can be expressed as I=E/R. Kirchhoff's two laws also reveal a unique relationship between current, voltage, and resistance in electrical circuits that is vital to performing and understanding electrical circuit analysis. In this course, participants will learn how to use these laws when working with direct current (DC) circuits.
