Q:

# What does Ohm

A:

Ohm's law states that as long as a conductor's ambient temperature does not change, the electrical current flowing through it will be equal to the voltage divided by the conductor's resistance. The basic formula for determining the electric current is written as I = V/R. Electric current is represented by "I," voltage by "V" and resistance as "R."

Electric current is measured in amperes, while voltage is measured in volts, and the resistance of a conductor is measured in ohms. Resistance is the property of a substance or an object to oppose the flow of electric current through it, and resistance will always remain a constant in its relationship with current and voltage. A substance exhibiting a high value of resistance, such as quartz, will oppose the flow of electrical current through it more than one with a lower resistance value, such as copper. Ohm's law is named after Georg Ohm, the German physicist who first published it in its original form in 1827.
