The Complete Beginners Guide to Arduino - 2021 - Resistance and Ohms Law

The video tutorial explains Ohm's Law, discovered by Georg Ohm in 1827, which describes the relationship between current, voltage, and resistance in an electric circuit. It covers the basics of electric circuits, including the flow of current, the role of voltage, and the concept of resistance. The tutorial introduces the standard units and symbols for these quantities and explains Ohm's Law equation (V=IR). Practical examples demonstrate how to apply the equation to calculate current, voltage, and resistance in various circuit scenarios.

What happens to the current if the voltage is increased while the resistance remains constant?
