2. Which equation represents natural transmutation?
A) I°B + He + 43N + on
B) WC + 4N + je
C) S + 2e + S2-
D) Na + Na+ + e-

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

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
