Question 1

Potential difference

Answer 1

• The difference in work done moving charge from infinity to point A and moving a unit charge from infinity to point B
• It’s the difference in work done moving a charge between two points
• the potential difference is found over a circuit and adds up to get the end

Question 2

Electromotive force

Answer 2

• Only exists in the source of energy

* the driving force across a power source

Question 3

Potential energy

Answer 3

The work done in moving a unit charge from infinity to a point

Question 4

Electron volt

Answer 4

Work done in moving an electron through a potential difference of 1 volt

Question 5

Coulomb’s law

Answer 5

The force of attraction or repulsion is affected by the distance so the bigger the distance the less the force of attraction
