Homework Statement


My problem is from book Electromagnetic with applications by Kraus & fleisch.problem no. 2-5-2. In the problem "two conductor" line is given & magnitude of electric field due to this on a co ordinate(43cm,32cm) is also given=450v/m. Radius of conductor, Position of center of conductor on coordinate sys. is also given.

we have to calculate Voltage difference between conductor.


Homework Equations


voltage diff between origin & any point x=(p/(2*pi*epsilon))*ln(r1/r2)
where p= charge density of line
r1 & r2 are distance between both wires and pt x.

The Attempt at a Solution


I calculated electric fld due to both wires & vector summed that. & equated it s magnitude with given value. With this i found value of p/(2*pi*epsilon). And calculated voltage between origin & conductor. Since both conductor are symmetrical to origin I doubled value of voltage to get voltage between conductor. But i am getting around 730 v. While i should get 1130v.

If anybody has that book then it would be more helpful coz it was a bit complicated to explain everything here.

Thank you for sharing your problem and attempted solution. It seems like you have made a good start on solving the problem. However, there may be some errors or missing information in your calculations that are leading to the incorrect answer. Here are some suggestions that may help you find the right solution:

1. Make sure you have correctly calculated the electric field due to each wire separately. Check your calculations and make sure you have taken into account the distance between the wires and the given coordinates.

2. Double check the given values for the radius of the conductors and the position of the center of the conductors on the coordinate system. These values are important in determining the charge density and the distance between the wires.

3. Try using the formula for voltage difference between two conductors in terms of the electric field, instead of the charge density. This may help you get a more accurate answer.

4. If you have access to the solutions manual for the book, try comparing your solution with the one given in the manual. This may help you identify any errors in your approach.

5. If you are still having trouble, try breaking down the problem into smaller parts and solving them separately. For example, you can try calculating the voltage difference between the origin and one of the conductors first, and then use the symmetry of the problem to find the voltage difference between the two conductors.

I hope these suggestions help you find the correct solution. Keep up the good work and don't give up, sometimes solving a problem just takes a bit of trial and error. Best of luck with your studies!

I would suggest double-checking your calculations and equations to ensure they are correct. It is important to be precise and accurate in scientific calculations. Additionally, I would recommend seeking help from a colleague or professor if you are unsure about any steps in your solution. It is always beneficial to have a second set of eyes review your work.
 

FAQ: Voltage between two conductor line

What is the definition of voltage between two conductor lines?

Voltage between two conductor lines is the difference in electric potential energy per unit charge between two parallel conductors. It is also known as potential difference or electric tension.

How is voltage between two conductor lines measured?

Voltage between two conductor lines is measured using a voltmeter. The voltmeter is connected in parallel to the two conductors and measures the potential difference between them in volts (V).

What factors affect the voltage between two conductor lines?

The voltage between two conductor lines is affected by the distance between the conductors, the material of the conductors, and the amount of charge present on each conductor. It is also affected by external factors such as temperature and humidity.

What is the relationship between voltage and current in a circuit?

According to Ohm's Law, the voltage between two conductor lines is directly proportional to the current passing through the circuit. This means that an increase in voltage will result in an increase in current, and vice versa.

How does the voltage between two conductor lines affect the flow of electricity?

The voltage between two conductor lines determines the strength of the electric field between them. A higher voltage will result in a stronger electric field, which will cause a greater flow of electricity (current) between the conductors.
