This video teaches the basics of Ohm's law, which is an important equation in electrical engineering. The three variables which are used in this equation are V, which stands for voltage, I for current, and R for resistance. The equation for the law itself is I=V/R. This law defines the relationship between these three very important electrical properties. The host of the video further explains what voltage, current, and resistance are and how they work in relation to an electrical current. Given two of the values, students should be able to plug in values to Ohm's Law and solve for the third value. This video seeks to give students a better understanding of this aspect of electricity.
