What else can I help you with?
Three different bulbs are connected in series when switch is closed the last bulb does not glow why?
When bulbs are connected in a series circuit, each bulb depends on the voltage from the previous bulb to light up. If the last bulb doesn't glow, it may indicate that there is a break in the circuit somewhere before that bulb, such as a loose connection or a blown fuse. This interruption in the circuit would prevent the flow of electricity to the last bulb, causing it not to light up.
What did you do to make light bulbs glow dimmer?
To make light bulbs glow dimmer, I reduced the amount of electricity flowing to them by using a dimmer switch or a lower wattage bulb. This decrease in electricity causes the filament in the bulb to emit less light, resulting in a dimmer glow.
Which bulb will glow at first when 3 bulbs are connected in series and switch is connected after 1 bulb?
The bulb that will glow first when 3 bulbs are connected in series and the switch is connected after 1 bulb is the second bulb in the series. The current flows through all the bulbs in a series circuit, but the second bulb experiences the full potential difference first as it is connected directly to the source.
What will be the order in which the bulbs of the same circuit glow when the switch is on?
All simultaneously. Unless the circuit includes special devices that you failed to mention to sequence them.
What are the light bulbs that use a wire to conduct heat to male it glow?
It might be the energy saving bulbs.
What happens to the bulbs in parallel circuit if one of the bulbs buns out?
The other bulb remain to glow with same intensity.
If you could see inferred light could you see a glow from the back of your eyelids when you closed your eyes?
Yes, you would see a glow from the back of your eyelids when your eyes were closed.
What did you do to make light bulbs glow brighter?
To make light bulbs glow brighter, you can increase the voltage supply to the bulb. This will cause more current to flow through the filament, resulting in a brighter glow. Be cautious not to exceed the recommended voltage rating of the bulb, as this can lead to overheating and damage.
How do fluorescent bulbs glow?
Fluorescent bulbs contain mercury vapor that emits ultraviolet light when electricity excites it. The ultraviolet light then hits a phosphor coating inside the bulb, causing it to glow and produce visible light.
What kind of energy transformation is a chandelier brightens a ballroom after a waiter moves a switch?
The energy transformation is electrical energy being converted to light energy. When the switch is moved, the electrical energy flows through the chandelier's circuit, causing the light bulbs to glow and illuminate the ballroom.
Why do the flimant in light bulbs not have oxygen inside?
because it doesn't let the light glow
What causes fluorescent bulbs to glow?
Fluorescent bulbs glow due to a process called fluorescence. Inside the bulb, a low-pressure gas (typically mercury vapor) is ionized by an electric current, producing ultraviolet (UV) light. This UV light then excites a phosphor coating on the inside of the bulb, causing it to emit visible light. The combination of these processes results in the characteristic glow of fluorescent bulbs.
