    How can i measure current ( with multimetar ) of 35V capasitor with 100uF
    capasity ?
    Should i connect resitor and how ?

    Terry, you have helped me very much! Thank you ! Sorry for long replay time.
    ****************************************
    This is the redefined question, an the problem:
    Im making some small test project where i want to control the discharge of
    fully charged capasitor ( this is the end part ).

    For start i need to understand this situation:
    Let's take stronger capasitor : 6000 uF at 18V

    - Capasitor will be charged thru 2x9V battery.
    - battery is common eu 9V battery (varta) and it is non rechargeable.

    1.) When i connect capasitor to battery and when capasitor is full he should
    have 18V

    Question:
    1.) How much current is on this capasitor ?
    2.) If i would use some different DC input ( 18V ~ 2mA ) to charge
    capasitor, how much current will be then, on this capasitor ?


    Basicly, i want to find out how to calculate current on the capasitor when
    you have constant defined voltage input (with low or very low current).


    Thank you in advance !

    First you need to understand better how to use the word 'current'.

    I agree. I have used this term from the last post.
    But you know what im asking and why :)
