Answer:
F=531831381
Explanation:
There are two ways of doing this question:
1) By Formula
2) By Using Compound interest Table
By Formula:
Where:
F is future value
A is annual amount per year
i is interest rate
n is number of years
F=531831381
By Using Compound interest Table:
F=A(F/A,i,n)
From Table F/A at i=8% and n=8 is 10.6366
F=50000000*(10.6366)
F=531830000≅531831381
The difference in two answers is due to decimal points if you take value from table to greater decimal points you will get the exact answer as by using formula.

Answer:
a. 30.O7A
b. no reading
Explanation:
for the first load with power factor 0.8, we calculate the reactive power
note the reactive power is calculated as
where p=power
a. for the first load the reactive power is
for the second load the reactive power is
The total reactive power is the summation of both reactive power in he load
and the total real power is 25kw
Hence using Pythagoras theorem to calculate the apparent power we have
Hence we can determine the source current using
b. in a balance 3phase system, there is no neutral current, Hence the ammeter will read zero current
