Question

Output of a transformer is connected to a lamp rated 6V, 1.8W and the input is connected to a 220V supply

Answer 1

The resistance of the filament of the lamp varies with temperature. When the filament is at room temperature the resistance is much lower than when it is white hot.

Current = V/R. If the voltage is constant and the resistance increases, the current decreases.
