Which has a larger resistance, a 60 watt lightbulb or a 100 watt lightbulb ?
Which has a larger resistance, a 60 watt lightbulb or a 100 watt lightbulb ?
Homework Answers
P=I*V
If V=230 V
for 100 W bulb,
100=230*I
I=100/230 = 0.43 A
Similarly for 60 W bulb
60=230*I
I=60/230 = 0.26 A
Low current High resistance.
Means 60 W bulb have more resistance

Which has a greater resistance: 75 watt bulb or a 100 watt bulb?
Which has greater resistance: a 75 watt bulb or a 100 watt bulb?Suppose you connect a 75 watt bulb across only 50 volts: will you still get 75 watts of power?Suppose you connect a 100 watt bulb and a 75 watt bulb in series and then connect the combination to a regular 110 volt line. Which bulb (if either) will burn brighter?(note that we are talking about the older incandescent bulbs here... the newer types are quite different.)
