40VI = IR" × I => 40V = IR" => 40× V/I = R" => 40R = R" Hence, the resistance of this bulb = R" = 40R For the 100-watt bulb: P = I 2 R = 0.24 2 * 144 = 8 W For the 40-watt bulb: P = I 2 R = 0.24 2 * 360 = 21 W This is actually an underestimate, but it does give us the relative brightness. R = Volts/Amps, 120/.33 = 363.6 ohms resistance. Good to know, I was trying to work out a bulb wattage by measuring the resistance of the filament, and was confused why the reading was 50ohm cold reading on a 250 volt supply that would have been almost 1kw, that's impossible for a G9 bulb as they only make them up to 60 watts. Neither bulb has 120 volts across it, but the key is that the resistance of the 40 W bulb is larger, so it dissipates more power and is brighter. What is the time signature of the song Atin Cu Pung Singsing? Pagkakaiba ng pagsulat ng ulat at sulating pananaliksik? Does Jerry Seinfeld have Parkinson's disease? Watts = Amps x Volts. Ano ang Imahinasyong guhit na naghahati sa daigdig sa magkaibang araw? What is the rising action of faith love and dr lazaro? b) find the current in the filament c) how much charge passes through the filament per minute d) how many electrons pass through the filament per minute e) If reliant charges $0.130 per kWH, how much would it cost to leave this light bulb on eight hours a day per month (30 days)? Awsome! .33 amps. Use a power equation to find the power for each bulb when they're in series with one another. On this calculation I am assuming that the light bulb is using a Hence, the resistance of this bulb = R' = 60R (ii) 40 W. Let the resistance of this bulb be R". What is the resistance of a 40 watt bulb? A similar calculation showed that the 40 W bulb has a resistance of 360 Ωat 120 volts. Ano ang pinakamaliit na kontinente sa mundo? 40W = VI.
