Does not glow.


Gets fused


Glow continuously.


Glow intermittently.​

Answer 1

Answer:

glow intermittently.

Answer 2

If an electric bulb rated 220 volts is connected 220 volt 50 hertz AC source, the bulb will glow intermittently.

• The bulb will not illuminate if the voltage is less than 220V, as this is the bare minimum.
• If a 220V bulb is given a voltage of 220V, its lowest value, the light will glow, but only intermittently.
• The bulb will fuse if a voltage much higher than 220V is applied to it.
