Current Electricity is an important part of the Physics section in the JEE Main entrance exam. It involves the study of electric current, its various components, and laws. The JEE Main Current Electricity Practice Questions with Solutions contain a lot of questions from this chapter, along with their solutions and the detailed explanations for each solution. You may expect about 2 to 3 questions on current electricity in the Physics section of the JEE Main question paper. Candidates must practice these questions on a frequent basis and refer to the solutions to clear their concepts regarding current electricity. This chapter is tricky, and therefore, sufficient time must be allotted to master this area. The important topics of current electricity include the following: Electric Current, Ohm’s Law, Electric Energy & Power, Electrical Resistance & Resistivity, Combination of Resistors, Drift Velocity and Mobility, Kirchhoff’s Laws, Circuits with Batteries & Cells, Wheatstone Bridge & Meter Bridge, and EMF, Potential Difference, & Internal Resistance.
The current electricity chapter consists of many laws and formulas which are important for solving numerical problems surrounding this subject. Practising the JEE Main Current Electricity Practice Questions with Solutions on a frequent basis will help JEE Main aspirants to remember the formulas well, as well as sharpen their problem-solving abilities. The JEE Main current electricity practice tests are an amazing resource for JEE Main aspirants to practice, as they consist of 15 to 20 questions from all important topics of this chapter, and all difficulty levels. Regular practice will also help the students improve their accuracy in solving numerical problems, boosting their scores in the Physics section. Students will also develop confidence during the real exam, as they’ll be well aware of the format of the questions asked in the JEE Main exam’s question paper.
