Two electric bulbs have ratings $P_1 \text{ watt}, V \text{ volt}$ and $P_2 \text{ watt}, V \text{ volt}$. If they are connected in parallel to a $V \text{ volt}$ supply,the total power consumed will be:
- A$P_1 + P_2 \text{ watt}$
- B$\sqrt{P_1 P_2} \text{ watt}$
- C$\frac{P_1 P_2}{P_1 + P_2} \text{ watt}$
- D$\frac{P_1 + P_2}{P_1 P_2} \text{ watt}$
