Electrical Design & Estimation Engineer Interview Questions and Answers for Freshers

Ampere's Law relates the magnetic field around a closed loop to the current passing through the loop.

• Ampere's Law states that the magnetic field around a closed loop is proportional to the current passing through the loop.

• It is one of Maxwell's equations in electromagnetism.

• The law is often used to calculate the magnetic field produced by current-carrying conductors or solenoids.

• Ampere's Law can be written in integral form as ∮B⋅dl = μ0I, where B is the magnetic field, dl is ...read more

Sag line is the lowest point on a transmission line where the conductor sags due to its own weight.

• Sag line is the lowest point on a transmission line.

• It occurs when the conductor sags due to its own weight.

• Sag in the line is important to consider for proper design and estimation.
