Ohm's law in electricity states that the current flowing through a conductor between two points is proportional to the voltage across them.
In other words, if the voltage is doubled the current will also double, but if the resistance of the conductor is doubled the current will only be half.
Ohm's Law Formula
Below is the mathematical formula for ohm's law:
π = πΌπ
- V = volts
- I = current in Amps
- R = resistance in Ohms
Here are different variations of the formula based around what values are known:
πΌ = π / π π = π / πΌ
