GENERAL KNOWLEDGE

Detailed explanation-1: -Ohm’s law states that current is directly proportional to voltage and inversely proportional to resistance. The voltage, current, and resistance formula is expressed as I=VR I = V R, where I is the current in amperes (A), V is the voltage in volts (V), and R is resistance in ohms ( ).

Detailed explanation-2: -In the first version of the formula, I = V/R, Ohm’s Law tells us that the electrical current in a circuit can be calculated by dividing the voltage by the resistance. In other words, the current is directly proportional to the voltage and inversely proportional to the resistance.

Detailed explanation-3: -Ohm’s law may be expressed mathematically as V/I = R. That the resistance, or the ratio of voltage to current, for all or part of an electric circuit at a fixed temperature is generally constant had been established by 1827 as a result of the investigations of the German physicist Georg Simon Ohm.

Detailed explanation-4: -In 1826 Georg Ohm discovered this relationship and developed a mathematical law of electric current. This is now known as Ohm’s Law. One way Ohm’s Law can be stated is: “a current flowing through a conductor is directly proportional to the voltage, given the temperature of the conductor remains constant".
