Which of the following statements are correct?

(A) The resistivity of a semiconductor decreases with increasing temperature.
(B) The potentiometer is unaffected by the internal resistance of the source.
(C) In ionic crystals and electrolytic liquids electrons carry the electric current.
(D) Ohm's law fails if V depends on I non-linearly.
(E) Kirchhoff's rules are used for analysis of electric circuits.

Choose the correct answer from the options given below:

(A), (B), (D) and (E) only

The correct answer is Option (2) → (A), (B), (D) and (E) only

(A) In semiconductor as the temperature increases, the number of charge carriers also increases due to thermal excitation, which leads to decrease in resistivity.

(B) A potentiometer is drawn in such a way that it does not depend on the current drawn from the source, and hence, it is unaffected by the internal resistance of the source.

(D) Ohm's law state's that the current through a conductor is directly proportional to the voltage across it.

(E) Kirchoff's current and voltage law are widely used to analyze complex circuit because these laws apply to both AC and DC circuit.
