Understanding Ohm's Law

The video tutorial explains how to calculate the current in a circuit using voltage and resistance, based on Ohm's Law. It introduces Georg Simon Ohm, who discovered the relationship between current, voltage, and resistance. The tutorial defines Ohm's Law, stating that current equals voltage divided by resistance, and provides an example calculation using specific voltage and resistance values to find the current.
