A) \[{{P}_{1}}+{{P}_{2}}\]
B) \[\sqrt{{{P}_{1}}{{P}_{2}}}\]
C) \[\frac{{{P}_{1}}{{P}_{2}}}{{{P}_{1}}+{{P}_{2}}}\]
D) \[\frac{{{P}_{1}}+{{P}_{2}}}{{{P}_{1}}{{P}_{2}}}\]
Correct Answer: A
Solution :
When two bulbs are connected in parallel, voltage across them will be same, hence equivalent power is \[{{P}_{eq}}={{P}_{1}}+{{P}_{2}}\]
