In the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv. the combination is defined as enthalpy: d. none of the above

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

they are made of gases.

they have a spherical shape.

they make energy through fusion.
