(c) Current remains constant
(d) Temperature remains constant.

Answer 1

Answer:

(c) current remains constant

Answer 2

Explanation:

Ohms law is valid only for linear elements. It shows a linear relationship between the applied voltage and the resulting current, resistance being a constant. Hence, the correct answer an option (c).
