There are two different solutions in set up P and Q as shown in figure. The bulb in the set up P glows more brightly as compared to that of the set up Q. What are the possible cause(s) for this?

(i) The connections of the circuit Q may be loose.
(ii) The liquid in Q may have small conductivity.
(iii) Liquid in Pis salted water while liquid in Q is tap water.

A

Only (i)

B

Only (ii)

C

Only (i) and (ii)

D

Only (ii) and (iii)

Text Solution

Verified by Experts

The correct Answer is:
