1. The problem statement, all variables and given/known data Question number 3!, I attached it. Need help! Figure 1 shows the current through and the voltage across a device. Find the total energy absorbed by the device fore the period 0<t<4. 2. Relevant equations integral of p = energy P=VI 3. The attempt at a solution Just need the algorithm to solving these kinds of problems, I am kind of thrown off at the instantaneous change.
