Module 6 - Capacitors

Question 1

What are capacitors?

Answer 1

electrical components that can store electrical charge

Question 2

define capacitance

Answer 2

the amount of charge it is able to store per unit P.D. across it
measured in farads (F)

Question 3

what is 1 farad?

Answer 3

equal to 1 coulomb per volt (C/V)

Question 4

what are capacitors used for?

Answer 4

1. flash photography - capacitors discharge very quickly to give a short pulse of high current which creates a short, bright flash
2. back-up power supplies -
