Impedance is the amount of alternating current impeded by the circuit; Admittance is reciprocal to it. Take the informative quiz by Gibilisco that gauges how much you know about the topic. Impedance and Admittance form one of the important topics that are usually asked in the exam. The quiz also provides you with valuable information. It has a wide coverage of easy, medium, to hard-level questions. So let's see how prepared you are to attempt these questions. If you find the quiz helpful, do share it with your friends. All the best!
