The Ohm's Law explains the relationship between electric current, voltage, and resistance.
Georg Simon Ohm discovered this law in 1827.
According to the law, electric current is proportional to the voltage and inversely proportional to the resistance.
The formula for Ohm's Law is I = V/R, where I is current, V is voltage, and R is resistance.
The formula can be used to predict the behavior of materials.
Resistivity, represented by the Greek letter ρ, is a component of resistance that considers material properties.
Resistance is directly proportional to the length and inversely proportional to the cross-sectional area of the conductor.
The unit of resistance is Ohm (Ω).
Ohm's Law is widely used in electrical engineering and physics.
Ohm's Law is applicable to both AC and DC circuits.
