Equivalent Power In series and parallel combination

Well the answer is very simple; If bulbs have 60W at 200V this means that the bulbs resistance is equal to: P = V^2/R ---> R = V^2/P = 200V^2/60W = 667Ω and because we have three light bulbs connected in series the total resistance is equal to 3*667 = 2kΩ so the total power is equal to P = 200V^2/2kΩ = 20W This means that the book give you the correct equation In any combination of resistors, after you find out the equivalent resistance , the total current across the combination and the total potential drop across the combination, you can write the effective power as any of the above two expressions ( given by you)
