A75.00 g sample of a substance is analyzed and found to consist of 32.73 g phosphorus and 42.27 g oxygen. calculate the percent composition of this substance.

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

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
