5.4 Capacitors

Question 1

Capacitance

Answer 1

Is the charge stored per unit volt
- C= Q/v

Question 2

Farad

Answer 2

One farad can be described as the capacitance which stores a one- coulomb charge across a p.d of 1 volt

Question 3

Time constant

Answer 3

The time taken for the p.d /Q /I to fall to 1/e of its initial value while a capacitor discharges.
