Which of the following laws states that electric current 'I' flowing through a metallic wire is directly proportional to the potential difference 'V', across its ends provided its temperature remains constant?

Which of the following laws states that electric current 'I' flowing through a metallic wire is directly proportional to the potential difference 'V', across its ends provided its temperature remains constant? Correct Answer Ohm's Law

CONCEPT:

  • Ohm’s law: At constant temperature and other physical quantities, the potential difference across a current-carrying wire is directly proportional to the current flowing through it.

V= RI

Where V is the potential difference, R is resistance and I is current.

EXPLANATION:

  • Ohm's law states that the current(I) through a conductor between two points is directly proportional to the voltage(V) across the two points.
  • Pascal's law states that any pressure applied to a fluid inside a closed system will transmit that pressure equally in all directions throughout the fluid.
