What is the difference between series and parallel Christmas lights?
With series Christmas lights, if one burns out, the whole string stops working. With parallel Christmas lights one light burning out only affects that light. This makes it much easier to replace burned out lights in the case of the parallel lights.
What is the principle of electric bulb?
The principle of an electric bulb( thee one with the filament ) is "RESISTANCE " it works just like a water immersion heater but at higher temperatures.. the filament inside the bulb offers high resistance to electricity or the electrons that try to pass, so due to high resistance proportionally high heat is produced (principle of immersion water heater), but how does it glow? have you seen how they make swords and metal items at a blacksmith the metal will actually glow red and then orange and turn to normal, and even sometimes molten hot metal look orange in colour, because, metals when overheated they emit light, and in our case of a electric bulb also the filament gets heated up and glows, and why use tungsten? why not any other metal? because tungsten has a melting point if about 3300 degrees celcius, that is way too high, so when the metal is heated to very high temperatures it does not break but emits light and also generates a lot of heat, that's why when you try to touch an incandescent bulb which has been burning for a long time it burns your fingers on contact, it will be hot, very hot. why do you think all over the world people are trying to get incandescent bulbs banned? it dissipates so much heat, 90% of electrical energy supplied to the bulb is turned into heat, that's why if you have a bulb lighting a closed fish tank the surface of the water feels warm!
How does a compact fluorescent light bulb work?
A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.
What causes a light bulb to go out when tightened in socket?
Because when a light bulb is tightened the stuff inside squashes then snaps, causing it to blow.
How hot is a 15 watt light bulb?
120
What is the effect on total resistance of adding this third bulb?
If a fourth bulb were added in a similar way to the three existing bulbs, the resistance in the circuit would go up if the bulbs were series connected, and it would go down if the bulbs were parallel connected.
How can you connect bulbs in series?
A Bulb can be connected in a series in such a way that the energy source which is applied want to flow equally across the bulbs connected in series. A Bulb has to knobes or holds in which we supply the power. Assume one knob as a positive voltage absorbing source and other has a negative voltage absorbing source. When we connected in such a way that we can apply the voltage continuously in which the bulb will blow easily. When two or more bulbs are connected in series like end of the knob of one bulb i.e., negative to the next positive of the next bulb in series and negative of second bulb to the positive of the third bulb. Then the voltage splits equally across the bulbs connected.
Light bulb in parallel circuit brightness?
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
Is it sensible for the TV to be connected in series with the light bulbs?
Connecting light bulb is equivalent to connecting a resistance. If you have connected light bulb, there will be some voltage drop across it and your TV may not get sufficient voltage. However if resistance is not big enough, than it wont have any effect.
The voltage for 4 bulbs in a circuit?
The circuit voltage or the resistance of the individual bulb is needed to answer this question. Divide the total power (400 W) by the supply voltage.
Are lamps in house connected to series or parallel?
They can be connected to either supply. A bulb in series that fails, will cause all the other bulbs to go out. A bulb in parallel that fails, will have no adverse effect on the other bulbs in that circuit
Which bulb will glow at first when 3 bulbs are connected in series and switch is connected after 1 bulb?
All the three would glow at the same instant.
Is this your experiment with physics?
· to show the effect on a bulb if a resistance is connected in series with it in the circuit.
Three bulbs of different watts are connected in series - which bulb will burn brightly - the higher wattage bulb or the lower?
lower wattage bulb
Two light bulbs of resistance R1 and R2 R2R1 are connected in series Which is brighter?
The brightness of a light bulb is related to its power. In all electrical circuits, power is equal to Voltage*Current. Since the two bulbs are connected in series, they must have equal current. The voltage across any given element in a series circuit is proportional to its resistance, so whichever bulb has the higher resistance has a higher voltage and thus higher power and is brighter.
Suppose in a circuit with two bulbsthe resistance of bulb 1 is greater than that of bulb 2how will the voltage across the two bulbs compare?
That depends on whether the bulbs are wired in series or in parallel.
What is the reason for bulb becoming dim when connected in series?
the voltage across it is reduced, the voltage is shared with other bulbs
