Ohm's Law can be rewritten in three ways for calculating current, resistance, and voltage. If a current I should flow through a resistor R, the voltage V can be calculated. First Version of the (voltage) formula: V = I Ã R. If there is a voltage V across a resistor R, a current I flows through it.
Ohm's law states that the voltage (V) across a resistor is proportional to the current (I), where the constant of proportionality is the resistance (R). For example, if a 300 ohm resistor is attached across the terminals of a 12 volt battery, then a current of 12 / 300 = 0.04 amperes flows through that resistor.
