An electric lamp of 100Ω, a toaster of resistance 50Ω, and a water filter of resistance 500Ω are connected in parallel to a 220 V source. What is the resistance of an electric iron connected to the same source that takes as much current as all three appliances, and what is the current through it?
Since the electric iron connected to the same source that takes as much current as all the three appliances. So
Resistance of the electric iron=125/4Ω=31.25Ω
Current through the electric ironu200b=7.04A
