circuit has a 2A fuse.What is maximum number of 60W (220V) bulbs that can be safely used in the circuit?​

Answer 1

★ Given Question :

• circuit has a 2 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 2A fuse

• ⟹ 60W (220V) bulbs

✯ Formula Used Here :

• ⟹ P = V × I

• ⟹ n = Power of circuit / power of bulb

★ Finding Power in Circuit :

• ⟹ I = 2A

• ⟹ V = 220V

✯ Putting value in formula :

• ⟹ P = 220 × 2

• ⟹ P = 440 watt

✯ Number of Bulbs ( 60 W ) :

• ⟹ n = Power of circuit / power of bulb

• ⟹ n = 440/60

• ⟹ n = 7.333 = 7 ( Approx)

★ 7 Bulbs of 60 W is Used in Circuit.
