Why do the readings of current differ(by 0.01 like that) for increasing and decreasing values of the incandescent and cfl lamp voltages?

Question

Vikas TU · Answer

The resistance of a incandescent lamp is non linear, therefore when cold resistance is low and then grows when it warms up so varying the voltage will vary the current and so vary the temp of the filiment and its resistance,this is the main reason that most lamps fail when first switched on because thats when most current flows until it gets hot. also, resistance is directly propr. to temp.
