Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the correct statement of Ohm’s Law?
A
R = IV
B
V = R/I
C
All are correct
D
V = IR
Explanation: 

Detailed explanation-1: -The correct answer is Voltage is directly proportional to Current. Ohm’s law is one of the most basic yet fundamental law in current electricity. It states that when a potential difference (V) is applied across a conductor it is proportional to the current (I) that flows through it (V ∝ I).

Detailed explanation-2: -Ohm’s law states that the voltage V is directly proportional to the current I, according to V = IR, where R is the resistance. Thus, a plot of voltage versus current is a straight line that passes through the origin.

Detailed explanation-3: -V=IR is the formula that gives you resistance, but it is a common misconception, that Ohm’s law is V=IR. Actually, Ohm’s law suggests that the current through a metallic conductor (kept at constant conditions, e.g., temperature) is directly proportional to the potential difference across its ends.
