what is the correct expression of the law of Ohm?
A
V = R/I
B
R = V*I
C
I = V/R
D
R = V*I
Explanation: 

Detailed explanation-1: -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-2: -Ohm’s Law is V = IR, where V = voltage, I = current, and R = resistance. Ohm’s Law allows you to determine characteristics of a circuit, such as how much current is flowing through it, if you know the voltage of the battery in the circuit and how much resistance is in the circuit.

Detailed explanation-3: -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.
