an area several km from an electricity generating station requires 120kw power on average the total resistance is line is 0.4 ohm calculate power loss if the transmission is made ata low voltage 240V

To calculate the power loss in the transmission line, we can use the formula:

Power Loss = (I^2) x R

Where:
I = Current
R = Resistance

First, we need to find the current flowing through the transmission line. We can use Ohm's Law:

V = I x R

Rearranging the equation to solve for I:

I = V / R

Given:
V = 240V
R = 0.4 ohm

I = 240V / 0.4 ohm
I = 600 A

Next, we can calculate the power loss:

Power Loss = (I^2) x R
Power Loss = (600 A)^2 x 0.4 ohm
Power Loss = 360,000 W

Therefore, the power loss in the transmission line will be 360,000 watts.

To calculate the power loss in the transmission line, we can use the formula:

Power loss = (I^2) * R

Where:
I is the current flowing through the line, and
R is the total resistance of the line.

First, let's calculate the current flowing through the line using Ohm's Law:

V = I * R

Where:
V is the voltage and
R is the resistance.

Given that the voltage is 240V and the resistance is 0.4 ohm, we can rearrange the formula to solve for current (I):

I = V / R

Substituting the given values:

I = 240V / 0.4 ohm
I = 600 Amperes (A)

Now, we can substitute this current value into the power loss formula:

Power loss = (600A)^2 * 0.4 ohm
Power loss = 360,000W or 360 kW

Therefore, the power loss in the transmission line is 360 kW.
