Answer 1

★ Given Question :

• circuit has a 10 A 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 10A fuse

• ⟹ 60W (220V) bulbs

✯ Formula Used Here :

• ⟹ P = V × I

• ⟹ n = Power of circuit / power of bulb

★ Finding Power in Circuit :

• ⟹ I = 10A

• ⟹ V = 220V

✯ Putting value in formula :

• ⟹ P = 220 × 10

• ⟹ P = 2200

✯ Number of Bulbs ( 60 W ) :

• ⟹ n = Power of circuit / power of bulb

• ⟹ n = 2200/60

• ⟹ n = 36.66= 37 ( Approx)

★ 37 Bulbs of 60 W Used in Circuit
