Answer:
The line voltage of the three phase network is 346.41 V
Explanation:
Star Connected Load
Resistance, R₁ = R₂ = R₃ = 18 Ω
For a star connected load, the line current = the phase current, that is we have

Whereby the the voltage across each resistance =
is given by the relation;
=
× R
Hence;
=
=
× R = 25 × 8 = 200 V
Therefore we have;
The line voltage,
= √3 ×
= √3 × 200 = 346.41 V.
Hence, the line voltage of the three phase network = 346.41 V.
Answer:
Comparison Between NC and CNC Machine
NC stands for Numerical Control whereas CNC stands for Computer Numerical Control. In NC Machine the programs are fed into the punch cards. But in CNC machine the programs are fed directly into the computer with the help of a small keyboard similar to our traditional keyboard
Explanation:
Answer:
38kJ
Explanation:
Final Energy= Total Energy at the beginning + Total energy added - energy lost
Final Energy = 12.5 + 500/1000 + 30- 5
= 38kJ
Answer:

Explanation:
