Electrical Engineering XYZ MCQs
Apart from the skin effect the non uniformity of the current distribution is also caused by:
- Bundled conductors
- Proximity effect
- Ferranti effect
- All of these
Correct answer: 2. Proximity effect
Explanation: Similar to the skin effect, the proximity effect also influences the current distribution in conductors, especially when multiple conductors are placed close to each other. When conductors are placed in proximity, the magnetic fields generated by the currents in one conductor affect the distribution of currents in adjacent conductors. This results in a non-uniform distribution of current density, particularly notable in high-current transmission lines or bundled conductors.
