How do you calculate charge quantisation?​

Quantisation is total charge by number of electrons.

q=ne

here q is quantisation

n is number of electrons

e is standard charge that is

e= 1.6 × 10power-19C

Explanation:

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
