Final answer:
To estimate the power lost in transmission, calculate the resistance of the transmission cables and use it to calculate the power lost. Then, divide the power lost by the total power supplied by the power company and multiply by 100%.
Step-by-step explanation:
In order to estimate the percentage of power lost in transmission, we need to calculate the resistance of the transmission cables. We can use the formula:
R = ρ * (L / A)
where R is the resistance, ρ is the resistivity (constant for a given material), L is the length of the cables, and A is the cross-sectional area of the cables.
Once we have the resistance, we can use it to calculate the power lost in transmission using the equation:
Power Lost = I^2 * R
Finally, we can calculate the percentage of power lost by dividing the power lost by the total power supplied by the power company and multiplying by 100%.
