The potential difference, V, across the ends of a given metallic wire in an electric circuit
is directly proportional to the current flowing through it, provided its temperature
remains the same. This is known as:
-
A.
Ohm's law
-
B.
Resistance law
-
C.
Newton's law
-
D.
Ampere's law
Correct Answer:
A. Ohm's law
Explanation:
Ohm's law states that the potential difference (V) across a conductor is directly proportional to the current (I) passing through it, provided physical conditions like temperature remain constant. This relationship is mathematically expressed as V = IR, where R represents the electrical resistance of the wire. Therefore, the statement describes Ohm's law.
