Two bulbs,as in the previous context ($40\, W$ and $100\, W$ bulbs rated at the same voltage),are connected in series to a $200\, V$ line. Then:

  • A
    The potential drop across the two bulbs is the same.
  • B
    The potential drop across the $40\, W$ bulb is greater than the potential drop across the $100\, W$ 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 bulbs is $200\, V$.
