Electromagnetism prac design

  1. Sep 12, 2010 #1
    Hi everyone, I'm trying to solve this prac design, but still don't know what to do, can anyone please give me some suggestions?


    You are given an old cardboard box from Faraday’s, the bargain supermarket for electrical enthusiasts (“Everyday Low Charges”). The box contains

    a battery,

    a digital voltmeter (which records voltage as a function of time),

    a digital ammeter (which records current as a function of time),

    an industrial capacitor,

    two copper plates,

    and several bits of copper wire.


    How to use these humble materials to perform the following experimental tasks:
    (a) measure the capacitance of the industrial capacitor; and
    (b) construct a second capacitor from the copper plates, whose capacitance equals that of the industrial capacitor.

    Do I have to do something like connecting circuit for short period to charge capacitor, then let it discharge or something like that?
    Can I connect capacitor straight to battary without resistor in the series circuit?
