How does the resistance of a 100w light bulb compare to the resistance of a 60w light bulb?

How does the resistance of a 60 W light bulb compare to that of a 100 W light bulb?

If the voltage of two bulbs is assumed to be the same, the resistance of the bulbs equals to V/100 and V/60 respectively. Thus, it is proved that the 60W bulb has higher resistance than the 100W bulb.

Which has more resistance 100W bulb or 60W bulb?

A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high.

Which has more resistance 100W bulb or 60W bulb and why?

For a give voltage V, P is inversely proportional to R. So the 60 W bulb will have more resistance than the 100 W bulb.

Which has a larger resistance a 60 W lightbulb or a 100 W lightbulb both light bulbs are to be used at 120v?

Therefore, 60 watt lightbulb has larger resistance than a 100 watt lightbulb.

Which has more resistance 100w bulb or 25w bulb?

Hence, resistance will be more for the given which is dissipating less power. Resistance is more for 25 Watt bulb.

Why is a 100w bulb brighter than a 60W bulb?

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. … The 100 W bulb has a smaller resistance, so it will be the brighter bulb.

Does higher resistance mean brighter bulb?

The higher the resistance to current in the wiring, circuitry, and bulb, the lower will be the current, lower the power, and lower the brightness. Conversely, lower resistance means more brightness.

Which is having more resistance a220v 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.

Is a 100w bulb brighter than a 60w bulb?

60-watt bulb produces 800 lumens of light (most widely used in households) 75-watt bulb produces 1,100 lumens of light. 100-watt bulb produces 1,600 lumens of light.

Which bulb has more resistance 100w or 200w?

<br> Reason : A 100 W bulb has more resistance than a 200 W bulb. … i.e., higher is the wattage of a bulb, lesser is the resistance and so it will glow bright.
