Question

WHAT OHMS 2ND LAW ? ​

Answer 1

Answer:

Abstract. Ohm's law relates voltage, current and resistance in electrical systems as V=IR. Newton's 2nd law relates force, mass and acceleration as F=ma.

Answer 2

Answer:

Ohm's second law is valid only if the electric current is evenly distributed in the section of the conductor.

$R=ρ \frac{ℓ}{S}$

• R is the resistence
• length is ℓ
• cross-section of area S.
