Experiment P: Charging a capacitor at a constant rate
Marks : ______________
Aim: To investigate how the charge on a capacitor is related to the p.d. applied across it by charging the capacitor at a constant rate.
Apparatus:
o Capacitor (electrolytic type) 500 ?F
o Microammeter 100 ?A
o Clip component holder
o Stop-watch
o CRO
o Connecting leads
Theory:
From definition, the capacitor C of a capacitor is found from
C = Q/V
Where Q is the charge stored on the capacitor and V is the potential difference across it.
==> Q = CV
==>
If a capacitor is charged up at a constant rate, i.e. , where I is a constant.
Then is also constant.
