An electric oven of 2KW power rating is operated in a domestic electric circuit(220v)that has a current rating of 5Amp. what result do you expect? Explain

It seems what you are asking about the electric energy consumed by the electric oven or the cost of running the electric oven for a particular time. 

 

For energy consumed

P = Energy consumed  / time 

E = P x t

E = 2000 x t

substitute any value of t to get energy consumed

 

For cost of running electric oven = Total Energy consumed x cost per unit of electricity
