Answer 2

Answer:

(1) Series. Power=55 W for two bulbs

(2)Parallel Power=220 W for (two bulbs)

Step-by-step explanation:

I first calculate the value of R for 2 identical bulbs using the formula: R=$V^{2}$/P. I got the answer of R=440 for each bulb.  In series connection, R(total)=R1+R2= 880Ω, the power calculated from this by using the equation P=V^2/R is 55W. In parallel connection, 1/R(total)=1/R1+1/R2 so ,R(total)=220Ω, the power calculated from this is 220 W
