Which has a larger resistance, a 60 W lightbulb or a 100 W lightbulb? Which has a larger resistance, a 60 W lightbulb or a 100 W lightbulb? There's not enough information to tell. The 100 W bulb. The 60 W bulb. Their resistances are the same.

Respuesta :

You really can't tell.

Power = I^2 × R = V^2 / R ( unit in Watt)

For P = I^2 × R

Where we have P directly proportional to R, increase in Power leads to increase in R

So if we have 100 will have higher resistance

For P = V^2/R

Power is inversely proportional to resistance.

So increase in Power leads to decrease in resistance.

60 watt will have a higher resistance.
