Very Interesting.

What are the EMF,voltage and current

what is adiffrent bettwen voltae and current

we have sources of electricity as EMF,voltage and current

good

Physics Lesson & definitions for the benefit of the creators of this product: Voltage = Joules / Coulomb The "cartoon " depicting the analogy of a water basin and E.M.F. of an electrical ckt. is partially correct, but inaccurately portrayed since mention is made of E.M.F. & "pressure" . A more accurate physical analogy, the elevation of the open basin or (accumulator) follows E=MGH ) would be representative of Potential Energy as analog to E.M.F. & thus a better illustration, not an open pipe / as shown fed by a pump, as implied in the illustration. The classical E.M.F. in such an electrical circuit is independent of the gravitational field.

this course is not at all clear, the grammar of the paragraphs and the way everything is worded makes it quite confusing

Did anyone who speaks English as a first language check over this course before it was put online? This is very poorly put together and totally distracting.

What is emf,Voltage and Current?

Emf means Electromotive force. current is the the flow of electricity through a device. Voltage is a quantitative expression of the potential difference in electrical charge between two points in an electrical field.
