Can you please explain Voltage,emf,Current,R and charge in brief.?

I dont understand the difference between voltage,emf and potential difference.Also do charge means motion of electrons or electrons are charges? And also what is current then?

Voltage and current are explained in the electronics class under the electricity lesson.

EMF is loosely explained under the inductor lesson.

I am not sure what you mean by potential difference.
