Ohm's law

Ohm's lawsays that in anelectrical circuit,thecurrentpassin throu areseestoratween twa pynts, is relate tae the sinderin o thevoltagevailyies at thae twa pynts, an inversely relatit tae theelectrical conductanceatween thae twa pynts. This relation is shawn in the follaein formula:

$R={\frac {V}{I}}$

whaurIis the current inamperes,Vis the potential difference involts,anRis a constant, meisured inohms,cried thereseestance.

The law wis diskivert byGeorg Ohman setten furth in 1827.
