About Ohm's Law
Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points. The law is named after German physicist Georg Ohm, who published it in 1827.
The mathematical representation is: V = I × R
- V = Voltage (measured in volts)
- I = Current (measured in amperes)
- R = Resistance (measured in ohms)
