Current Electricity Charging Discharging Of Capacitors Question 475
Question: Two bulbs are in parallel and they together consume 48 W from a battery of 6 V. The resistance of each bulb is
Options:
A) $ 0.67,\Omega $
B) $ 3.0,\Omega $
C) $ 4.0,\Omega $
D) $ 1.5,\Omega $
Show Answer
Answer:
Correct Answer: D
Solution:
The bulbs are connected in parallel, hence each bulb consumes $ \frac{48}{2}=24,W. $
Therefore $ \frac{V^{2}}{R}=24, $
Therefore $ R=\frac{6\times 6}{24}=1.5,\Omega $
