capacitance and inductance

Question 1

capacitor

Answer 1

device that stores electrical charge. Opposes low frequency/DC flow as negative charge builds up on one plate and flow stops if polarity not reversed (which is won’t be in DC current)

Question 2

capacitance

Answer 2

ability to store electrical charge, farads

Question 3

Farad

Answer 3

a capacitor with a capacitance of one farad will store one coulomb of charge when one volt is applied to it
F = C/V

Question 4

electrical current

Answer 4

flow of electrons

Question 5

inductor

Answer 5

device that opposes change in current flow, allows passage of DC and low frequency AC more freely than high frequency AC. The higher the frequency (rate of change of current), the more back electromotive force generated that opposes the flow of current

Question 6

inductance

Answer 6

abaility to generate resistive electromotive force (V) under influence of changing current
