#### Transcript of Ohms law

OHMMMMM!
Why?
He was a German physicist who discovered the law, named after him, which states that the current flow through a conductor is directly proportional to the potential difference (voltage) and inversely proportional to the resistance.
The basics of Ohms law.
Why is he important?
Ohm's Law defines a linear relationship between voltage and the current in an electrical circuit, that is determined by the resistance.

Ohm's Formula
The resistance R in ohms (Ω) is equal to the voltage (V) divided by the current I in amps (A): Since the current is set by the values of the voltage and resistance, the Ohm's law formula can show that: If we increase the voltage, the current will increase.
Georg Simon Ohm
Born March 16, 1789, Erlangen, Bavaria [Germany]
He studied mathematics and physics at Erlangen University.
Died at 64 years old July 6, 1854,Munich

Impaction of today?
Electrician's use Ohms Law everyday without Ohm's Law you wouldn't have electricity in your house or public places. You wouldn't be able to charge your phone, tablet, or computer. You couldn't microwave your food.
