Potential difference and capacitance

Question 1

Experiment for charge by induction

Answer 1

You charge an object uses static electricity and bring it close to a conductor

You then earth the conductor, then you remove the charge object

Question 2

Point discharge

Answer 2

Large accumulation of charge at pointed part of object

air around the point is ionised meaning opposite ions will be attracted and like ions will repel causing an electric wind

Question 3

capacitance =

Answer 3

Perm(Area) over distance

Question 4

Capacitance (definition)

Answer 4

C = Q over V

Question 5

Potential difference

Answer 5

work done per unit charge
