SAMPLE QUESTIONS FOR ENTRANCE TEST

JEE

NOTE : For each question, you will be awarded 4 marks if you darken the bubble corresponding to the correct answer ONLY and zero marks if no bubbles are darkened. In all other cases, minus one (–1) mark will be awarded in this paper. Out of the four options in each question only one option is correct. 1. Between which two junctions a battery is connected to the circuit shown in order to deposit charge on all the six capacitors having equal capacitance C (1) A and B (2) C and D (3) A and D (4) None of these 2. A capacitor of capacitance C is charged by connecting it to a battery of electromagnetic force E volts. The capacitor is now disconnected and reconnected to the same battery with polarity reversed. The heat energy developed in the connecting wire is (1) CE2 3.
