Ohm's law
Ohm's law
Ohm's Law states that for a conductor at a constant physical state, the ratio of the voltage (V) applied across its ends to the current (I) flowing through it remains constant. This constant ratio is called the resistance (R) of the conductor.
Ohm's Law allows us to calculate the values of voltage, current, and resistance in a circuit. We can use it to find any one of these variables if the other two are known..
