Question

graph between electric current and potential difference across two conductors A and B are shown which of the two conductors has more resistance

Answer 1

V = R × I
R = V / I
Let the potential is constant , then R is inversely proportional to I.
In the graph , for a particular voltage current of B is more than current of A
Therefore , resistance of B is less than of A
R(A) > R(B)

Answer 2

Answer:

The correct answer is B.

Explanation:

• B conductor possesses more resistance as compared to that of A.
• The current in conductor B is greater than the current in conductor A for command voltage V.
• From Ohm's law, $R=\frac{V}{I}$
• Hence, Resistance is inversely proportional to that of current.
• Electric current is defined as the movement of electrons through a whole circuit of conductors known as electric current. Everything from our lights to our trains is powered by it.
• A substance's ability to obstruct the flow of electrical current is referred to as resistance. It is symbolized by the capital letter R. The ohm, which can be written as a word or represented by the uppercase Greek letter omega, is the universal unit of resistance.
