[NCERT 1971, 78]
Options:
A) The potential drop across the two bulbs is the same
B) The potential drop across the 40 watt bulb is greater than the potential drop across the 100 watt bulb
C) The potential drop across the 100 W bulb is greater than the potential drop across the 40 W bulb
D) The potential drop across both the bulb is 200 volt
Show Answer
Answer:
