an electric generator is rated 12 kilowatt, 2 kilovolt distribute power through a cable of resistance of 20 ohms through the cable calculate the power loss
Power loss can be calculated using the formula:
Power loss = I^2 * R
Where:
I = Current flowing through the cable
R = Resistance of the cable
First, we need to calculate the current flowing through the cable. We can do this using the formula:
Power = Voltage * Current
12 kW = 2 kV * I
Therefore, current flowing through the cable (I) = 12 kW / 2 kV = 6 A
Now we can calculate the power loss:
Power loss = 6 A^2 * 20 ohms = 240 W
Therefore, the power loss through the cable is 240 watts.
