Which has higher resistance 50 watt or 25 watt?
As R=V2/P,R∝1/P. Thus, a25W lamp has double the resistance of a 50W lamp.
Which has a higher resistance a 50W lamp or a 25W 220v lamp?
Under a constant fixed applied voltage V R2>R1 25W bulb has higher resistance. Resistance of 25 W lamp bulb is twice the resistance of 50W lamp bulb.
Which has a higher resistance a 100 W bulb or 25 W bulb and by how many times?
ANSWER: 25W has the highest resistance.
Which has higher resistance a 50 watt bulb or 2.5 watt bulb and how many times?
R – 1/ r – 2 ⇒ 50 / 2.5 ⇒20 times. So 2.5 watts is 20 times more than 50 watts of bulb.
Which of the two has higher resistance?
By ohm’s law, resistance is inversely proportional to the current. Greater the current, less is the resistance. Among 1kw=1000w bulb and 100w bulb, 100w bulb has greater resistance.
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 one is having lesser resistance a 220v 60W bulb or a 220v 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 bulb has more resistance 100W 220v or 60W 220v?
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 higher resistance ammeter or Milliammeter?
For a constant voltage , the current through a milliammeter must be lower (in the order of milliamperes) but the current through a ammeter would be higher (in the order of amperes) thus the resistance in milliammeter will be higher.
Which of the two has greater resistance a two kilowatt heater or a 100 watt bulb both marked for 220V?
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.
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 of the lamp has more resistance?
