Question

which bulb will glow more ?a)bulb A (100 w ,220 v)b)bulb B (200 w,220 v)c)bulb C (50 w, 220 v)
sure answer with explanation ​

Answer 1

Answer:

bulb C will glow more brighter than bulb A and B .

Explanation:

1. a) P = V^2÷R R = PV^2 = 100×220×220 = 4840000 ohm
2. b) R = PV^2 = 200×220×220 = 9680000 ohm
3. c) R = PV^2 = 50×220×220 = 2420000 ohm

therefore , because C bulb has lowest resistance , which gives greator flow of current and with larger current , the bulb will glow brighter .

HOPE YOU GET THE RIGHT ONE!!!!!✌
