Given below are two statements:
Assertion (A): If two identical bulbs of resistance are connected in series to a voltage source , the total power dissipated is . If they are connected in parallel to the same source , the total power dissipated is . Then .
Reason (R): In series combination, the equivalent resistance is higher, leading to less current and thus less power dissipation compared to the parallel combination across the same voltage source.
Options:
Answer:
A
Solution:
For series and parallel connections:
At fixed voltage, higher equivalent resistance means lower power.
Both statements are true; the Reason explains the Assertion. Answer A.
