1. The problem statement, all variables and given/known data The current flowing through an element is i = 2 A for 0<t<1 and i = 2t^2 A for t>1 Calculate the charge entering the element from t=0s to t=2s. Answer: 6.667 C. 2. Relevant equations I used Q=t1∫t2 i dt 3. The attempt at a solution I tried to solve using integral method. but how to proceed here as for 0<t<1 i is constant and i am stuck. Are there any other methods.
