A) \[{{R}_{A}}<{{R}_{B}}\]
B) \[{{R}_{A}}={{R}_{B}}\]
C) \[{{R}_{A}}>{{R}_{B}}\]
D) none of these
Correct Answer: A
Solution :
Since, bulbs A and B are connected in parallel, therefore the potential across both the bulbs is same i.e., \[V={{i}_{A}}{{R}_{A}}={{i}_{B}}{{R}_{B}}\] But bulb A glow more than bulb B Therefore, \[{{i}_{A}}>{{i}_{B}}\] Hence, \[{{R}_{A}}<{{R}_{B}}\]You need to login to perform this action.
