Which Bulb Will Glow Brighter 100W Or 200W?

Explanation: 100w bulb has more resistance than 200w bulb. Hence 100w bulb will glow with less brightness than 200w bulb.

Why does a 200W bulb glow brighter than a 100W bulb?

Assertion : The 200 W bulbs glows with more brightness then 100 W bulbs. Reason : A 100 W bulb has more resistance than a 200 W bulb.

Which bulb has more resistance 100W or 200W?

Assuming that both bulbs are rated for the same voltage, the bulb with lower power will have higher resistance. Therefore 100W bulb has more resistance.

Why the 500W bulb glows with more brightness than a 200 W bulb?

Now,the input in the first stage (electrical energy) is the result behind the product of the second stage (light energy). Now, greater the amount of the input is given in the first stage will produce greater the amount of the product in the second stage. That’s why 500W bulb glows brighter than 200W bulb.

Which bulb will glow more brighter?

The bulb which dissipates more power will glow brighter. In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness.

Which is having more resistance a 220V 100W bulb or a 220V 60W bulb?

Answer: The 220V, 60W bulb has more resistance. R = 220*220/100 = 484ohm (approx.) So, Case 2 has more resistance.

Which bulb has more resistance 100W or 60W?

As P=V2/R,P∝1/RorR∝1/P. Thus, the resistance of 60W bulb is more than that of 100W bulb.

Which bulb has least resistance 100W or 60W?

Since the voltage will be the same for both light bulbs, using the formula, the bulb with the lowest resistance would have the greatest power. Hence 100 watt bulb has less resistance.

Which bulb will glow brighter 60W or 100W?

The resistance of the bulb is given by R=V2/P. So the resistance of 60 W bulb is more than the resistance of 100 W bulb. When they are connected in series the current through both bulbs is same. Hence 60 W bulb will be more brighter because P = I2R.

Which is brighter 60W or 100W?

Answer: The bulb rated at 100 W will be brighter. When both bulbs are connected to the rated voltage, they will dissipate the rated power. The brightness of a bulb depends on the power it dissipates, so the 100 W bulb will be brighter than the 60 W bulb.

Which bulb will glow first?

bulb C
(a) bulb C will glow first.

Which electric bulb has the least resistance a 60 watts B 100 watts C 200 watts D 500 watts?

Power rating of bulb is given by P = V²/R. For all bulb value of V will be same because they are connected to same potential difference. 1/P. So resistance of 1000W bulb will be least.

When electric bulb is rated 220V and 100W?

Solution. R = 220²/100 Ω = 484 Ω. This is the resistance of the bulb. When V = 110 V, power consumed = V²/R = 110²/484 = 25 W.

Which one has more resistance 100 watt bulb or 60watt bulb both operating at 220V?

Answer: The resistance of 60 watt bulb is greater than the resistance of hundred watt bulb.

Which draws more current 100W?

So higher voltage drop will be across a 60W bulb. In parallel voltage drops will be same across both the bulbs but current through it will be inversely proportional to the resistance. So 100W bulb draws more current than 60W bulbs.

Does a brighter bulb have more resistance?

If both bulbs are running at rated voltage, the brighter bulb will be a higher wattage bulb, and that will have lower resistance. But if you mean two identical bulbs, with one on a dimmer, the one on the dimmer will have a lower resistance.

Do higher watt bulbs have higher resistance?

A higher watt bulb allows more electricity through, therefore the resistance must be lower.

How much resistance does a 100 watt light bulb have?

The typical cold resistance of a 100 W incandescent lamp is about 9.5 ohms. If that resistance stayed the same with 120 V applied, Ohm’s Law tells us that the bulb would draw about 12.5 amps and dissipate about 1,500 watts.

Which has higher resistance a or B?

The slope of a V-I graph represents resistance. And, the resistance is higher for series combination as compared to that of a parallel combination. In the figure given, we observe that B has higher slope and hence higher resistance. Therefore, A represents the parallel combination.

Which bulbs will have high resistance?

Power is inversely proportional to the resistance. So 60 W bulb has more resistance.

Which circuit has brighter bulbs A or B?

1. When all bulbs are lit, bulb A is the brightest and bulbs B and C are equally bright. 2. If you unscrew A, bulbs B and C remain the same.
