    Is electrical engineering just rote memorization? Or am I

    For instance, I was introduced to thevenin and norton theorems about 1-2 weeks ago and it seems like we're expected to rote memorize the algorithms on solving problems. There is no proof/logic explained in different circumstances. For instance, we're told what these theorems are and how they...
