b is the correct answer

Answer:

(B) Voltage = Current × Resistance

Explanation:

Ohm's law states that the voltage is directly proportional to the current flowing. Mathematically, it can be written as:

\(V\propto I\)

\(V=IR\)

R is the constant of proportionality and it opposes the flow of electric current in the wire called as the resistance.

In terms of length and the area of cross section of the wire the resistance can also be written as :

\(R=\rho\dfrac{l}{A}\)

\(\rho\) is the specific resistance or resistivity

l and A are length and the area of cross section

So, the correct option is (B) " Voltage = Current × Resistance ".
