46.3 wt%a, 23.15 wt%b and 30.55 wt%c. assume the densities in g/cu. cm of a, b andc are 2.68, 5.86 and 10.39, respectively. determine the approximate density in g/cu. cm if the alloy is composed of

Answer : The approximate density is

Explanation :

The formula used to calculate the density of the mixture is,

where,

= density of mixture = ?

= mass of fraction of component A = 46.3 % = 0.463

= mass of fraction of component B = 23.15 % = 0.2315

= mass of fraction of component C = 30.55 % = 0.3055

= density of component A =

= density of component B =

= density of component C =

Now put all the given values in the above formula, we get:

Therefore, the approximate density is

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
