We're supposed to create a visual representation of a chemical reaction using bubbles and include the charges on ions. the reaction is Ca(NO3)2(aq)+ Na2SO4(aq)= NaNO3(aq)+ CaSO4(S). I have the first part done.

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

i believe that it is a exoplanet
