Ohms law, VIR - Skill badge, iron-on patch

You learned and used Ohm's law! Adafruit offers a fun and exciting "badges" of achievement for electronics, science and engineering. We believe everyone should be able to be rewarded for learning a useful skill, a badge is just one of the many ways to show and share.

This is the "I learned Ohm's law" badge for use with educators, classrooms, workshops, Maker Faires, TechShops, Hackerspaces, Makerspaces and around the world to reward beginners on their skill building journey!

This beautiful badge is made in the USA and has subtle details like metallic thread.

The badge is skillfully designed and sturdily made to last a life time, the backing is iron-on but the badge can also be sewn on.

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance one arrives at the usual mathematical equation that describes this relationship. I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.
