Concept explainers
The ratio of power transformed in the first relative to the second.
Answer to Problem 69GP
Explanation of Solution
Given info:
Voltage,
Length,
Diameter,
Formula used:
Where, P is the power,
Resistance:
Where,
Calculation:
By using the expression of power:
It is known that the two conductors are connected to the same voltage of
So,
By using the formula of resistance, form a new expression
From equation
It is known that the two conductors are form the same material. This means that they have the same resistivity. Substitute the values of equation
From the given values:
Conclusion: The ratio is
