प्रश्न

State Ohm’s law.

थोडक्यात उत्तर

उत्तर

Ohm’s law states that electric potential difference across two points in an electrical circuit is directly proportional to the current passing through it. That is,
V~I
The proportionality constant is tne resistance (R) offered between the two points.
Hence, Ohm’s law is written as,
V = RI (or) V = IR
Where, V is the potential difference in volt (V), I is the current flow in ampere (A), R is the resistance in ohm (Ω)
