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 is having more resistance a 100 W bulb or a 60 W bulb operated at 220 Volt?
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.
Why does a 100 watt bulb gives more light than a 60 watt bulb?
In short, the 100W bulb is brighter because it is giving off more energy than the 60W bulb. This energy is in the form of electromagnetic radiation , which includes visible light, but also other parts of the spectrum such as infrared and UV light. More energy = more light, hence brighter.
Which has a greater resistance a 100 W 110v bulb or a 60W 200v bulb?
60W bulb has higher resistance than 100W bulb. It is because power is written on the bulb assuming that voltage is same (say for example 230V). Therefore according to formula P = V^2/R, lower the power rating higher will be the resistance.
Which is having more resistance 220V 100W?
Answer: The 220V, 60W bulb has more resistance. R = 220*220/100 = 484ohm (approx.)
Which is more brighter 100W or 60W?
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.
Is 100 watts brighter than 60 watts?
Here is a breakdown of traditional watt light bulbs and the amount of light they produce in lumens: 40-watt bulb produces 450 lumens of light. 60-watt bulb produces 800 lumens of light (most widely used in households) … 100-watt bulb produces 1,600 lumens of light.
Which light is brighter 60W or 100W?
In Short, the voltage drop across 60W bulb is more than 100W because 60W bulb has higher resistance. Hence 60W bulb will glow brighter.
What is the resistance of 100 watt bulb?
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 of the following has higher electrical resistance?
The material that has the highest electrical resistance is silver. After silver copper and gold are the materials that have the highest electrical resistance.
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.
Which has more resistance a 50W bulb or a 100W bulb when connected to the same potential of 220V?
Answer Expert Verified
we can say the resistance of bulb is inversely proportional to power consumed. So bulb with 50W has more resistance.
Which has greater resistance an electric heater having rating 220V 1000w or an electric bulb having 220V 100W?
Electricity. Which of the two has greater resistance: a 1 kW heater or a 100 W tungsten bulb, both marked for 230 V? Thus, the 100 W bulb has greater resistance. An electric lamp of 100 Ω, a toaster of resistance 50 Ω, and a water filter of resistance 500 Ω are connected in parallel to a 220 V source.
Which of the following bulbs will have high resistance * A 220V 60W B 220V 100W C 115V 60W D 115V 100 W?
