★ Given Question :
- circuit has a 5A fuse.What is maximum number of 60W (220V) bulbs that can be safely used in the circuit?
★ Required Solution :
✯ Values Given to us :
- ⟹ circuit has a 5A fuse
- ⟹ 60W (220V) bulbs
✯ Formula Used Here :
- ⟹ P = V × I
- ⟹ n = Power of circuit / power of bulb
★ Finding Power in Circuit :
- ⟹ I = 5A
- ⟹ V = 220V
✯ Putting value in formula :
- ⟹ P = 220 × 5
- ⟹ P = 1100 watt
✯ Number of Bulbs ( 60 W ) :
- ⟹ n = Power of circuit / power of bulb
- ⟹ n = 1100/60
- ⟹ n = 18.33 = 18 ( Approx)
✫ 18 Bulbs of 60 W is Used in Circuit.
