Which of the following correctly describes the electrical charges of subatomic particles? B Protons/positive; neutrons/negative; electrons/negative

C Protons/neutral; neutrons/positive ; electrons/negative

D Protons/negative; neutrons/neutral; electrons/negative

D Protons/negative; neutrons/neutral; electrons/negative

Explanation:

There are three fundamental subatomic particles found in atom which are the protons, neutrons and electrons.

In the tiny central nucleus, both protons and neutrons can be found

The electrons occupy the bulk volume of the atom.

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
