Question

Ohm’s law states which relationship between electrical quantities? ( )

(a) Potential difference = Current times resistance

(b) Potential difference = Current divides resistance

(c) Potential difference = Charge divides current

(d) Potential difference = Charge times resistance​

Answer 1

Ohm's Law states (a) Potential difference = Current times resistance.  

What is Ohm's Law?

• Electrical conductors obey Ohm's Law.

• According to this law, potential difference across a conductor is directly proportional to the current flowing in the conductor.

V ∝ I

V=IR

V represents potential difference which is applied across the conductor

I represents current flowing in conductor and

R, a proportionality constant represents resistance of the conductor.

SI unit of resistance is given Ohm (Ω), unit of current is ampere and unit of voltage is Volt.
