Answer Posted / md. obaydur rahman
All the above answers are wrong because we know that for a
constant power rating,
P=V*I
i,e. I=P/V
From the above equation we can see that if the voltage
changes the current is also changed for a constant power
rating i,e. if voltage reduced the device draws more current
to consume its power rating and vice versa.
