Network -- Current passing through a capacitor

[anand raj]

Homework Statement

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

Homework 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

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?

 

[Simon Bridge]

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.
