Question

Two bulbs marked 200 W-250 V and 100 W-250 V are joined in

series to 250V supply. Power consumed in circuit is

Answer 1

P = 300 [W]

Step-by-step explanation:

The mark of 200 W - 250 V, means that the bulb has a power of 200 [W] and must be connected at a voltage of 250 [V]. Regardless of whether the bulbs are connected in Series or in parallel, the total power is the sum of the powers of each bulb.

`P=200+100\\P=300[w]`
