# Ohm's Law

Ohm's Law is a law that describes the relationship between voltage, current, and resistance. Using algebraic operations the law can be used to solve for I, V, or R, and expressed in the following ways:

Where V = Voltage in volts

I = Current in amps

R = Resistance in ohms

Solve for volts:

$V = IR$

Solve for resistance:

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

Solve for current:

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