Answer 1

The formula for Ohm’s law can be written: V equals  l x R

Answer: Option A

Explanation:

Ohm's law defines that an electric current flowing through the conductor between two ends is directly proportionate to the voltage at these two points. The introduction of a constant proportionality, resistance, gives a simple mathematical equation describing this relationship. Particularly, Ohm's law also mentions that R is constant in this respect i.e. independent on current.

                        $\text {voltage }(V)=\text { current }(I) \times \text { Resistance }(R)$

Where,  

I is the current conduction in amperes

V is the voltage calculated by the conductor in volts

R is the conductor’s resistance in ohms.
