electrical appliance which is labelled " 240V, 2000W "

If you have an electrical appliance which is labelled " 240V, 2000W ",

What will happen if you plug it to an electrical source of 250V? Will it get burned? What will happen if you plug it to an electrical source of 230V? Will it work?

That depends on the appliance. In most cases, I would think it would be fine. Some modern power supplies for appliances are tolerant of an extremely wide range of input voltages (~90-260 V or so).
 


Nothing would happen if the voltage supplied is lower, right? Except may be the appliance won't work till the required voltage is supplied?
 


Considering the electrical appliance as a simple form of resistive load, such a slightly high voltage than rated capacity should not burn it but if the voltage applied is very high, then definitely it will burn the appliance, (unless protected by some other sophisticated mechanism). Similarly, lower voltage would give lower output from the appliance.
