    5. Electric current is considered as the flow of electrons whereas flow of protons is considered as conventional current. Electrons travels from negative terminal to positive terminal.But why does the flow of electric current is from positive to negative terminal

    Ans 1 ->
    When concept of current was discovered it was known that a positive entity is responsible for flow of I so many law and appliances where made cosidering I to be from + to - but to change it many things about electrodynamics have to be changed feeling many chance scientists kept it same

    7. Okayso I am confused According to the Quantization of Chargewe gotta write the net charge in the form of the integral multiple. But in the previous video we saw that the net charge on the body was +4C. What am I missing? Is it that this property is applicable only when the body consists of electrons only? I am confused Pls help.

    Ans 1 ->
    No... 4 could can be written as a multiple of one electron charge... think again... this is a very large qty charge compared to electronic charge...
