Dear sageer!

Although you have not specified the class assuming that you are asking important questions for electricity class 10 I will recommend you checking some questions.

1. Firstly you can check NCERT exemplar problems as they help in understanding the concepts clearly. You can check the NCERT question from https://school.careers360.com/ncert/ncert-solutions-class-10-science-chapter-11
2. Secondly I will recommend you to solve the previous year question papers from class 10th as they will provide you can real overview of type of questions asked in exam. You can find the questions from sample question papers for electricity from:
