Class 12 | Physics | Capacitance |Find equivalent capacitance between A and B in the combination given below.

 

 

(ii) Q=CV to get the charge

and U=Q^2/2C to get the energy

Class 12 | JEE Advance 2016 | Capacitance | The circuit given below The key is pressed at t=0 which of the statement are true - A) The voltmeter displays − 5 V as soon as the key is pressed, and displays + 5 V after a long time B) The voltmeter will display 0 V at time t = ln 2 seconds C) The current in the ammeter becomes 1 / e of the initial value after 1 second D) The current in the ammeter becomes zero after a long time.

 

Class 12 | Physics Capacitance | A fully charged parallel plate capacitor is connected across an uncharged identical capacitor . Show that the energy stored in the combination is less than stored initially in the single capacitor

 

In the given picture, the capacitor plate are clamped in the labrotary and connected to a battery, length and width of each plate are l and b respectively, the dielectric experience an attractive force due to non uniform electric field between the capacitor plate the edge of the dielectric, calculate the value of weight of the block for which the dielectric will stay in equilibrium. Here all surface are frictionless
