Question

Find the true statement. (A) Ohm's law is applicable to all conductors of electricity (B) In an electrolyte solution, the electric current is mainly due to the movement of electrons (C) Specific resistance of a wire depends upon its dimension (D) The resistance of carbon decreases with the increase of temperature

Tardigrade Admin · Accepted Answer

Carbon is an insulator and has a negative temperature co-efficient. Hence, its resistance decreases with an increase in temperature.

Q. Find the true statement.

Ohm's law is applicable to all conductors of electricity

In an electrolyte solution, the electric current is mainly due to the movement of electrons

Specific resistance of a wire depends upon its dimension

The resistance of carbon decreases with the increase of temperature

Carbon is an insulator and has a negative temperature co-efficient. Hence, its resistance decreases with an increase in temperature.
