An electrolytic cell Group of answer choices consumes electrical current to drive a nonspontaneous chemical reaction. produces electrical current from electricity. produces electrical current from a nonspontaneous chemical reaction. produces electrical current from a spontaneous chemical reaction. consumes electrical current to drive a spontaneous chemical reaction

produces electrical current from electricity. produces electrical current from a nonspontaneous chemical reaction.

Explanation:

An electrolytic cell converts electrical energy into chemical energy. Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. The reaction at the anode is oxidation and that at the cathode is reduction. Here, the anode is positive and the cathode is the negative electrode.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
