What type of bond would h2 form? a- ionic b-metallic c-polar covalent d-non-polar covalen

C - Polar Covalent

A is incorrect as it is not a bond between a metal and non metal.

B is incorrect as a metal bond is a bond between the same element that is a metal; Hydrogen is a nonmetal.

D is incorrect as H2 is polar instead of nonpolar. This is due to the fact that the electrons are equally shared in the bond, making the compound polar.

Hope this helps!

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
