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.
How does changing voltage across a lamp affect the power consumption of the lamp?
because it does!
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.
Why do bulbs get dimmer in series circuits?
When light bulbs are connected in series circuits, they will get dimmer whenever a bulb is added. This is because the current is shared between all of the bulbs equally.AnswerLamps only operate at their rated power when subjected to their rated voltage. If you connect lamps in series, each lamp will be subject to a lower voltage, so they will not operate at their rated power and, so, will be dimmer. The more powerful lamps will actually glow less than the less-powerful lamps because their resistance is lower and the voltage drop across them will also be lower than the voltage drop across the less powerful lamps.
Can a 120V light fixture be used in India?
It can be if you connect two same watt lamps in series with each other. The 240 volt supply will drop 120 volts across each lamp.
What happens to a voltage as the Christmas lights are connected in series?
Divide the number of lamps into the value of the supply voltage, and that will tell you the voltage drop appearing across each lamp. Bear in mind that if one of the lamps should be removed, the full supply voltage will then appear across the empty lamp holder.
If four lamps are connected in series to a 3 volt battery how many volts are impressed across each lamp?
If all four lamps are identical, there will be an identical voltage drop on each. 3 volts / 4 lamps = 0.75 voltage drop at each light.
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.
If a 12 volt parallel circuit has 4 lamps and each lamp consumes 1 amp what is the resistance of each lamp?
Assuming you mean the 4 lamps are in parallel with each other: the total voltage drop across each lamp is still 12V. As we know that V= IR (Voltage = I Current times Resistance) 12 = 1 x R so Resistance = 12 Ohms for each lamp.
Why do two lights connected to one switch get dim?
Because when two lights use the same battery, both lights need the same power to work, so the power has to split in half making the bulb's brightness dimmer. Ridiculous. If the lamps are connected in series, they will be dim because half the available voltage is dropped across each lamp. In parallel, they will both have full brightness.
Why does 2 bulbs glow less brighter in series connection and more brighter in parallel connection?
Because in series they split the voltage. Two resistors in series have half the voltage. In parallel they have the same voltage and draw current according to their individual resistance.AnswerFor a lamp to operate at its rated power, it must be subject to its rated voltage. For example, two 120-V lamps will operate at full power when connected in parallel across a 120-V supply, because each branch of a parallel circuit is subject to the same supply voltage.If the same lamps were connected in series across a 120-V supply, each would be subject to a voltage drop of 60 V, resulting in each lamp burning dimly.However, two identical 120-V lamps would operate at full rated power if connected across a 240-V supply, because the voltage drop appearing across two identical lamps will be 120 V. However, if the two lamps had different power ratings (and, therefore, different resistances), one voltage drop would be higher than the other, causing one lamp to burn brighter than the other. Since the lamp with the higher power rating has the lower resistance, the greater voltage drop would appear across the lower-power lamp which would burn brighter than the higher-power lamp.
In a circuit of two lamps in parallel if there is a voltage of 6 V across one lamp what is the voltage across the other lamp?
6 Volts.
When the three bulbs of sixty watts each is connected in series what is the formula used to calculate the total power?
The tree bulbs in series get each 1/3 of the usual voltage. Power is proportional volt squared. Each bulb uses then SQR of 60 = 7.746 watts. The total power will be 3 times 7.746 watts = 23.238 watts.
What happens to the voltage of a series circuit as you add bulbs to the circuit?
For any lamp to operate at its rated power, it must be subject to its rated voltage. If you connect, say, three identical 120-V rated lamps across a 120-V supply, then each lamp will be subject to one-third of its rated voltage. As a result each lamp will not be able to achieve its rated power. If the lamps have different power ratings, then it is rather more complicated, with the most powerful lamp becoming the dimmest while the least powerful lamp becoming the brightest.

What happens to the light bulbs in a series circuit?
The brightness of a lamp depends on its power rating, which is printed on the globe. This power rating onlyapplies at its rated voltage (e.g. 120 V in North America, and 230 V in Europe). When you connect lamps in series, you are connecting their individual resistances in series, and a voltage drop will appear across each lamp. For example, if you had, say, two 60-W lamps connected in series with each other across a 120-V supply, then 60 V would appear across each lamp, so the lamps would be considerably dimmer than their power ratings would suggest.The drop in power is not proportional to the drop in its rated voltage; it is considerably higher. It can be shown that for electric heaters, for example, a 10% drop in rated voltage causes a 19% drop in power! This is not necessarily the case for lamps, as their resistance changes significantly with temperature.If the lamps were of different power rating, then the lamps with the greater power rating would be dimmer than those with the lower power ratings -which is not what you might expect.
