please help, show every single of the solution.
thank you in advance!
5) a) What is the current in a 50 W the filament of a light bulb when you turn the light on? Electric sockets supply electricity at about 110 V b) How much charge does flow through the filament during 20.0 second? c) How many electrons pass during this time? d) What is the resistance of the filament? ej What is your monthly payment if you keep the light bulb on for 4 hours every day? The cost of each kW (kilo watt) is 55 cents. (Give your answer is dollars.)Explanation / Answer
(a) P = VI
=> I = P/V = 50/110 = 0.4545A
(b) I = Q/t
=> Q = It = 0.4545*20 = 9.09C
(c) n = Q/e = 9.09/(1.6*10^-19) = 5.68*1019
(d) R = V/I = 110/0.4545 = 242 ohm
(e) Total energy E = 50W * 4*30 hrs = 6000 Wh = 6kWh
Cost = 6*55cents = 330 cents = $3.3
