Why is it necessary to be extremely careful when working with barium chloride dehydrates

Explanation:

It is necessary because if you drop it on a human hand, it will eat the flesh off your skin and not stop unless you become dust.

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

i think it is true since you can test the answer and can use observations to complete it.
