#V = I * R# or other forms...

Explanation:

Ohm's law describes the relationship between voltage, current and resistance.

It can be expressed in the form: #V = I * R# where #V# is the voltage (measured in volts), #I# the current (measured in amperes) and #R# the resistance (measured in ohms).

This is also expressible in the VIR triangle:

which can be read as:

#V = I * R#

#I = V / R#

#R = V / I#
