IIT JEE : Capacitor QUESTIONS AND ANSWERS :: part1 : 1 to 5
Following IIT JEE Entrance Multiple choice objective type questions and answers will help you in Maths, Physics and Chemistry 2024 examinations :
1.A parallel plate capacitor (of capacity C ) is charged using a battery of potential V, It is disconnected from the battery and the plates of the capacitor are moved away from each other. Now it is reconnected to the same battery. Then |
| charge flows flows from the capacitor to the battery |
| charge flows from the battery to the capacitor |
| there is no flow of charge |
| the direction of flow of charge depends on the values of V and C. |
2.An air capacitor of 6pF is immersed in an oil whose dielectric constant is 2.0. The capacitance of one oil capacitor will be |
| 2.5 pF |
| 8.5 pF |
| 22 pF |
| 12.0 pF |
3.A parallel-plate capacitor is held horizontally so that one of the plates is submerged in the liquid while the other is above the surface of the liquid. A constant potential difference is applied between the plates. The level of the liquid between the plates will |
| rise |
| fall |
| remain unaffected |
| oscillate |
4.A parallel plate capacitor is charged and the charging battery is then disconnected. If the plates of the capacitor are moved farther apart by means of insulating handles, |
| the charge on the capacitor increases |
| the voltage across the capacitor plates increases |
| the capacitance increases |
| the electrostatic energy stored in the capacitor decreases. |
5.A parallel plate capacitor is made by stacking n equally spaced plates connected alternately. If the capacitance between any two plates is C then the resultant capacitance is |
| C |
| nC |
| (n - 1) C |
| (n + 1) C |
