How many moles is 17.gg NaOH

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

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

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

well in order to answer this question you have to provide more information < 3
