    hi,
    i wanted to ask the the following question
    the current entering the terminal of an element is given by equation
    i(t)=(10^6)*(t^2)-(10^7)*t
    the total charge flowing into the element will be??
    please explain the answer.
    thanks.. :)

    This looks like homework as well.

    Read this, again.

    Charge (Q) equals Current (I) times Time (t)

    Can you do the algebra for the next step to answer your question, or do you need help there as well.

    i did integrate current with respect to time to find the charge but my answer is not in accordance with the answer given on answer sheet.

    How can we explain an answer you haven't given?

    How can we find what you did wrong when you haven't shown what you did?

    We are NOT mind readers!

    So integrating the current would give:

    Then how did you apply the integral basic form?
