An electric lamp of 100 `Omega `, a toaster of resistance 500 `Omega`, and a water filter of resistance 500 Ω 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?
