A stove, a toaster, and a flat iron are connected in parallel to the main line which provides a potential difference of 220 volts. If the resistance of the toaster is 20 Ω, the flat iron 25 Ω, and that of the stove 40 Ω, find the amount of current flowing in each device the total current through the main line the combined resistance of all three devices
