Text Solution
Verified by ExpertsThe correct answer is:
A
Resistance 
of 500 W bulb 
Resistance 
of 200 W bulb 
When joined in parallel, the potential difference across both the bulbs will be same.
Ratio of heat produced 
When joined in series, the same current will flow through both the bulbs.
Ratio of heat produced
