What is the Inductance of Parallel Wires in a Circuit?

Click For Summary
SUMMARY

The inductance of two parallel wires in a circuit can be calculated using the formula μ₀/π(L*ln((w-r)/r) + w*ln((L-r)/r). In the discussion, the user attempted to compute the inductance for a loop with a length of L=2m, width w=5cm, and wire radius a=1mm, arriving at a value of 3.3*10^-6 H. However, this value was questioned for its accuracy, indicating a need for further verification or adjustment in the calculation method.

PREREQUISITES
  • Understanding of electromagnetic theory, specifically inductance.
  • Familiarity with the formula for inductance in parallel wires.
  • Basic knowledge of logarithmic functions and their application in physics.
  • Ability to manipulate and substitute values into mathematical equations.
NEXT STEPS
  • Review the derivation of the inductance formula for parallel wires.
  • Explore the impact of wire length and spacing on inductance values.
  • Investigate the effects of wire radius on inductance calculations.
  • Learn about practical applications of inductance in circuit design.
USEFUL FOR

Electrical engineers, physics students, and anyone involved in circuit design or analysis, particularly those focusing on inductance in parallel wire configurations.

1. Two wires running parallel to each other in a circuit can provide an inductance that is adjustable with their length. For the loop shown below with length L=2m , width w=5cm , and wire radius a=1mm , find the inductance in H?

Homework Equations

3. I thought i could find the inductance by using the equation mu0/pi(L*ln((w-r)/r) + w*ln((L-r)/r) and i found 3.3*10^-6 but it don't seem good.
Could you help me?
