The efficiency of the turbine is 50%.
The given parameters:
- <em>Kinetic energy of the wind, E = 3000 J</em>
- <em>Output electrical energy, E(out) = 750 J</em>
- <em>Energy lost to heat, E(lost) = 750 J</em>
- <em>Kinetic energy of the turbine, E(in) = ?</em>
The kinetic energy of the turbine which is the input energy is calculated as follows;
E(in) = 3000 - (750 + 750)
E(in) = 1500 J
The efficiency of the turbine is calculated as follows;

Thus, the efficiency of the turbine is 50%.

Answer:
(G) 75.11 ohm
(H) 0.08 A
(I) 46.2 degree
Explanation:
R = 52 ohm
L = 4.8 m H = 4.8 x 106-3 H
C = 330 nF = 330 x 10^-9 F
Vo = 6 V
(G)
f = 5000 Hz
Let the impedance is Z.




(H) Let Io be the peak current

(I) Let Ф be the phase angle


Ф = 46.2 degree
