How to Increase Mobile Battery Life in Android II Kya App Ke Mobile Ki Battery nhi chalti #shrots

The rechargeable battery used in a mobile phone hand set is usually:

When the chemicals in the electric cell are used up, the electric cell stops producing electricity. The electric cell is then replaced with a new one. In case of rechargeable batteries (such as the type used in mobile phones, camera and inverters), they are used again and again. How?

Separation between the plates of a capacitor is increased from d to 2d while the battery remains connected with the plates. How will the stored energy in the capacitor change?

Two parallel plate capacitors 8.0 mu F each , are connected in parallel to a 10V battery. One of the capacitors is then squeezed so that its plate separation is 50.0% of its initial value. Because of the squeezing, (a) how much additional charge is transferred to the capacitors by the battery and (b) what is the increase in the total charge stored on the capacitors?

You have a parallel plate capacitor, a spherical capacitor and a cylindrical capacitor. Each capacitor is charged and then removed from the same battery. Consider the following situations : I:· Separation between the plates of parallel plate capacitor is reduced II: Radius of the outer spherical shell of the spherical capacitor is increased Ill: Radius of the outer cylinder of cylindrical capacitor is increased. Which of the following is correct?

A statement followed by some conclusions are given below. Statement: owadays, life has become very difficult without a mobile phone. Conclusions: I. Total number of mobile subscribers is increasing. II. Mobile has become an integral part of life. Find which of the given conclusions logically follows from the given statement.
