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

Answer 1

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.
