Ohm's Law
Ohm’s Law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Mathematically, it can be expressed as:
I = V / R
Where:
I = current (in Amperes)
V = voltage (in Volts)
R = resistance (in Ohms)
This simple relationship forms the foundation for many electrical and electronic applications and is widely used in the design, analysis, and troubleshooting of electrical circuits.
