When I visit family in India, I usually need an adapter to use my US bought electrical devices (hair dryer, toothbrush etc) because the voltage from the wall outlets in India is 220V, not the 110V we get here in the US. The adapter is basically a Step Down transformer that takes an input of 220 V and gives an output of 110 V. If the primary (input) col in the adapter has 100 turns, how many turns should the secondary (output) coil have?
