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 one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb calculate?
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 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 one has more resistance a 100 W bulb or a 60 W bulb both operating at 220 V?
Which one has more resistance 100 watt bulb or 60 watt bulb both operating at 220 V The resistance of 60 watt bulb is
greater than
the resistance of 100 watt bulb.
Which has less resistance a 100 W bulb or a 60 W bulb?
In case of 100 watt bulb, it consumes more electricity than 60 Watt bulb which makes it clear that, the bulb with
100 Watts
has less resistance than the bulb with 60 Watts.
What is the resistance of a 60 watt light bulb?
In fact, the 120-Watt bulb would have a current of 1 Amp and a resistance of 120 Ω; the 60-Watt bulb would have a current of 0.5 Amp and a resistance of
240 Ω
.
Which one is having lesser resistance a 60 watt bulb or a 40 watt bulb?
Which one is having lesser resistance, a 60W bulb or a 40W bulb? if v is constant. Hence
bulb of higher voltage will have less resistance
. In other words, resistance of 60W bulb is less than the resistance of 40W bulb.
Which bulbs will have high resistance?
Incandescent light bulbs
have a small filament which when heated begins to glow and emit light. The reason the filament heats up is because it has a high resistance, which means that as electrons move through the filament, they lose a lot of energy.
Does higher resistance mean brighter bulb?
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.
Does higher wattage mean more resistance?
A higher watt bulb allows more electricity through, therefore the
resistance must be lower
.
When electric bulb is rated 220V and 100w?
Solution. R = 220
2
/100 Ω =
484 Ω
. This is the resistance of the bulb. When V = 110 V, power consumed = V
2
/R = 110
2
/484 = 25 W.
Which has more resistance 60W 220V or 100w 220V bulb?
Answer: The
220V
, 60W bulb has more resistance. R = 220*220/100 = 484ohm (approx.) So, Case 2 has more 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 thick or thin wire?
The
resistance of a thin wire is greater than the resistance
of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional .
What is the resistance of a 100 watt light 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.
Is a 100-watt bulb brighter than a 60-watt 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.
