## Physics MCQ on Series and Parallel Circuits for NEET, JEE, Medical and Engineering Exam 2021

MCQ on Series and Parallel Circuits: Previous trends reveal that NEET/JEE aspirants find Physics as the most challenging section amongst the other sections. But most of them fail to decipher the reason behind this. This particularly can be as the candidates taking up this examination are predominantly medical aspirants with their subject of interest being Biology. Also, sections like Physics are more on theories, laws, numerical as opposed to Biology which is more of fact-based, life sciences and comprising of substantial explanations. In this post we are providing you MCQ on Series and Parallel Circuits, which will be beneficial for you in upcoming NEET, AIIMS, JEE, WBJEE, Medical and Engineering Exams.
