Answer 1

Hey there!!

Your ans is-electrons flow because of electrical attraction and repulsion.

Hope you get it

Answer 2

Answer:

The best explanation of ‘electric current’ in a wire can be defined as Electron flow because of ‘electrical attraction and repulsion’.  

Explanation:

Current can be defined as the flow of electrons. When the electron charges get attracted and the current flow happens. When the ‘positive and negative’ charges get attraction to electrodes the process of the current flow begins.

Repulsion is a force between two similar things. Attraction is the force between two ‘dissimilar charges’. The attraction or repulsion acts along with two charges.
