If the wattage of each bulb is 1.5 w , what will be the reading in the ammeter A when all the three bulbs glow simultaneously.

A

1.5 Ampere

B

1.0 Ampere

C

0.1 Ampere

D

0.5 Ampere

Text Solution

Verified by Experts

The correct Answer is:
B
When the bulbs are in parallel, wattage will be added (4.5 W) and the ammeter reading would be,
`:. I = P/V =(4.5 W)/(4.5V) = 1.0 ` Ampere
