network theorem

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
