A 40W bulb or a 60W bulb will glow more brighter if connected in series?

The 40-W lamp will be the brighter, because it has a greater resistance that the 60-W lamp and, therefore, will experience a greater voltage drop across its terminals. The closer the voltage drop is to the lamp's rated voltage, the brighter it will be.


Why does a 25 watt bulb glow brighter than 60 watt in a series circuit?

Because the filament of a 25-W lamp has a higher resistance than that of a 60-W lamp and, therefore, will experience a greater voltage drop -the lamp with the voltage drop closer to its rated voltage (in this case, the 25-W lamp) will be the brighter.


Can you plug a 220V. 800Watt lamp into 240V?

Yes, but you will get a higher wattage output than 800 watts, this means that the lamp will glow brighter. This connection will also shorten the life of the lamp because of the higher voltage. When you state "plug", it suggests that the connection will not be made if the plug can not fit into the receptacle.


What is the relationship between the speed of a bicycle and the brightness of its lamp?

Why sodium lamp is prefer on white lamp during night?

The white lamp has a softer glow for evening hours.


What is brighter 60 Watt 110 volt or 60 Watt 220 volt?

If the voltage supplied to the lamps is its operating voltage both lamps will have relatively the same output in brightness. If the 60 watt 110 volt lamp is used on a 220 volt supply, it will glow very brightly and then the lamp's filament will burn open. If the 60 watt 220 volt lamp is used on a 110 volt supply, the lamp will glow at half brightness, but it will last for a very long time before the filament burns open.


Does a lamp get brighter if it is nearest to the energy source?

It depends on how they're connected, but in general : NO.

How do you test glow plug bob cat?

Several ways. Firstly make sure you are getting voltage to the glow plug. The easiest way is to connect a 12v lamp between the battery negative and the top of the glowplug. Turn the ignition on and the lamp should light. If lamp does not light the glow plug relay circuit has a problem. If lamp test OK remove it from the negative terminal and connect to the positive terminal of the battery. If lamp lights, glow plug OK. OR turn the ignition on for ten seconds and switch off again. feel the connector the top of the glow plug and it should be warm. OR disconnect wire and check with a meter between the glow plug contact and the engine block, the ohmic value should be less than 10.


Can you use a 5 watt bulb in a 4 watt light?

If the socket threads of the lamp are the same then yes the bulbs can be interchanged. The 5 watt bulb will glow brighter than the 4 watt bulb. If by a 4 watt light you mean a 4 watt fixture, then it is not recommended to place a larger wattage lamp in a fixture that is rated by the manufacturer at a specific operating wattage


How much brighter is a star than a lamp?

stars are planets and it shines because light is reflected so...depends on what kind of lamp ur talking about


Which bulb will glow brighter two bulbs of rating 100w-220vand200w-220v are connected in a series to a supply of 22ov?

For a lamp to operate at its rated power, it must be subject to its rated voltage. The lower the voltage, the lower the resulting power. In fact, a small drop in voltage will cause substantial drop in power. Higher 'wattage' lamps have lower resistance values than lower 'wattage' lamps.So, if you put two lamps in series, the greater voltage drop will appear across the lamp with the greater resistance. In your example, that means the 100-W lamp will be subject to the greater voltage drop, and its loss of power will be less than that of the 200-W lamp. So the lower power lamp will be the brighter of the two.
