Question


In the described experimental setup, a bulb connected to the electric circuit does not glow because

  1. The bulb may be fused
  2. The liquid used in the above experiment may be a strong electrolyte
  3. The liquid used in the above experiment may not be conducting electricity
  4. Both [b] and [c]

hintHint:

The bulb doesn't glow if the liquid connected to it is a weak electrolyte or a non-conducting solution.

The correct answer is: Both [b] and [c]


    • A strong electrolyte conduct an electric current as it has free ions.
    • A solution must be electrolyte to conduct current.
    • If the bulb is connected with a weak electrolyte or a non-conducting solution, it doesn't glow.
