A 4-watt light is plugged into a 120-volt circuit and operates continuously for a 30 day month. How much current does it draw.What is the resistance of the filament. app. much energy used in a month?
Current:For the 4-watt light, (volts) x (current) = 4.Current = 4/120 = 33 and 1/3 milliamperes.Resistance:Power = E2/R.R = E2/P = (120)2/4 = 3,600 ohms.Energy in 1 month:4 watts = (4 joules/second) x (86,400 seconds / day) x (30 days / month)= (4 x 86,400 x 30) (joule - second - day / second - day - month)= 1,036,800 joules= about 0.3 kWh (rounded)
