Question 16:
Two lamps, one rated 100 W at 220 V, and the other 60 W at 220 V, are connected
in parallel to electric mains supply. What current is drawn from the line if the supply
voltage is 220 V?
Answer:
Both the bulbs are connected in parallel. Therefore, potential difference across
each of them will be 220 V, because no division of voltage occurs in a parallel
circuit.
Current drawn by the bulb of rating 100 W is given by,
Similarly, current drawn by the bulb of rating 100 W is given by,
