Network -- Current passing through a capacitor

  1. Aug 30, 2014 #1
    1. The problem statement, all variables and given/known data

    A current i(t) as shown in the figure is passed through a capacitor. the charge (in micro coulomb) acquired by the capacitor after 5 micro seconds

    2. Relevant equations

    here slope is given for 3 microsecond ie. current=dq/dt = 2.5 charge upto here = 3*2.5=7.5 micro seconds do not know what to do/unable to interpret

    3. The attempt at a solution

    Your class notes (or google) have an equation relating the capacitor voltage to the integral of its current. What is this equation?

    The amount of charge accumulated between time ta and time tb is the area under the current-time graph between those times. It's like when you used v-t graphs to find displacement.
