What Is Ohm's Law?
Ohm's law is one of the most important laws of all electronic circuits or systems. The law show the relationship between voltage, current, and resistance. The definition of Ohm's law is "the principle that the electric current passing through a conductor is directly proportional to the potential difference across it, provided that the temperature remains constant. The constant of proportionality is the resistance of the conductor". This means that the current passing through a conductor increases if the voltage increases. If resistance is increased, the current decreases. This is correct if the temperature remains constant.
0.1 v, 0.4 amps, 254 Ω
4.5 v, 17.7 amps, 250 Ω
Voltage increases, increasing current.
9.0 v, 35.4 amps, 250 Ω
Voltage greatly increases, greatly increasing current.
