Is the filament resistance lower or higher in a 500 watt light bulb than in a 100 watt bulb?

There is more current needed to heat up the wire, thus also the power will be higher. Resistance = Volts divided by Amps. So, filament resistance for a 500 W bulb is lower than a 100 W bulb at the same voltage.

Do higher wattage bulbs have lower resistance?

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

Does higher wattage mean more resistance?

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 a larger resistance a 60w light bulb or a 100 W light bulb?

Take the voltage to be 230V for both the bulbs. Therefore, 60 watt lightbulb has larger resistance than a 100 watt lightbulb.

Which bulbs will have high resistance?

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.

What is the resistance of a bulb at 500w 220V?

The resistance of the electric bulb is 484 ohms.

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 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.

What is the resistance of the ELectric bulb rated 120w 220v?

484 Ω
R = 2202/100 Ω = 484 Ω. This is the resistance of the bulb.

What is the resistance of bulb 100w 220v?

100w at 220v, I=P/V. =100/220=0.454Amp. R=V/I; 220/0.454=484.56 ohms.

Is a light bulb with lower resistance brighter?

An incandescent bulb’s brightness depends on a whole lot on resistance. 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.

What is the difference between a 60W and 100W light bulb?

Assuming both bulbs are designed to operate at the same voltage V, then it’s obvious that the higher the bulb’s power rating P, the lower its resistance R, thus the 100W bulb has a lower resistance than the 60W bulb. Hopefully this is intuitively apparent as well.

What is the resistance of a 100 watt light bulb?

The current is the same through the bulbs, so consider: We already showed that the resistance of the 100 W bulb is 144 Ωat 120 volts. A similar calculation showed that the 40 W bulb has a resistance of 360 Ωat 120 volts.

What is the resistance of a filament lamp?

Resistance of a Filament Lamp. The current through a filament lamp is not directly proportional to the potential difference. This is because the filament gets hot, which causes the resistance to increase. At high temperatures, the atoms in the filament vibrate more. The electrons in the current now collide more with the atoms.

What is the Ohm rating of a 60 watt bulb?

110 / .5454 = 201.66 ohms for 60 watt bulb. Without formulas, the qualitative understanding is that the bulb consuming the most power is the one with more current, and thus less resistance, fewer ohms. E = I * R where E is potential in volts, I is current in amperes, and R is resistance in ohms.
