The practical use of the electric current problems is met basically everywhere even if you are not majoring in Engineering. Take an example of data programming and the use of safety (data transfer) questions when the data is being transferred from place to place via cloud storage solutions. The same is related to automation and logistics where the electric current equation will help to calculate the limitations and the available resources. See some answers to the questions dealing with the electricity principles to get a better idea of how it works and compare the existing solutions to your task objectives!
