(a)The emf at the generates end of the lines
(b)Fraction power loss in the lines.
Answer to Problem 33P
Solution:
(a)Emf = 49 Kv
(b)Fractional power loss = 0.36
Explanation of Solution
Given info:
Power = 35MW = (arrives at the town)
Voltage (rms)=
[Since rms = root square for defining current of AC wave]
Resistance(ohm)= 4.6Ώ.
(a) Formula to be used:
Using the formula of power,
P = Workdone by unit time
P = VI
Calculation:
Applying values in power formula,as we need current first.
The current in wire, (ohm’s law)
E = IR + v [E =Emf ]
(b) Formula to be used:
The power loss in the lines ,
Calculation:
Fractional power loss
% fractional power loss=
