Circuit

Question 1

What is a current?

Answer 1

1. movement of + charge over a period of time
2. flows from high potential to low potential ( from the charges being far apart to the charge coming close together)

Question 2

Which way does current flow?

Answer 2

1. From a region of high potential to a region of low potential

Question 3

What are batteries?

Answer 3

1. devices that allows to ease the unusual flow od electrons, by creating a potential between the charges that otherwise wouldn’t happen
2. Provides a emf : electron motive force is the force created by the battery to establish a potential that wouldn’t otherwise be there.
   
   1. make electron move from low potential to high potential ( going against the normal) flow.

Question 4

How does electron flow in terms of voltage?

Answer 4

1. Electron flow from anodes to cathode and the voltage is the energy generated by the need to overcome that potential from the two ends of a system.
