Ohm's Law

Ohm Law

Ohm's law give de relations between Voltage, Resistance and Current in pure resistive circuit through two points.

Formula

V = RI R = V I I = V R V=RI newline R=V over I newline I=V over R

Elements

  • I : Current, Ampere ( A )
  • R : Resistance, Ohm ( Ω )
  • V : Voltage, Volt ( V )

Examples:

V=50 Volts
I=2 Amps
Resistor=?
R=V/I=50/2=25Ω
