Ohm's law

Frae Wikipedia, the free beuk o knawledge

Ohm's law says that in an electrical circuit, the current passin throu a reseestor atween twa pynts, is relate tae the sinderin o the voltage vailyies at thae twa pynts, an inversely relatit tae the electrical conductance atween thae twa pynts. This relation is shawn in the follaein formula:

whaur I is the current in amperes, V is the potential difference in volts, an R is a constant, meisured in ohms, cried the reseestance.

The law wis diskivert by Georg Ohm an setten furth in 1827.
