Battery and EMF (Hindi)

Rajesh Kumar
In this lesson we have discussed about battery and EMF . battery is responsible for mentaining potential difference between two terminals. these two terminals are called positive terminal and negative terminals . positive terminal is made by accumulation of positive charge and negative terminals made by negative charge . battery force acting on positive charge in the battery solution . Work done by battery is equal to battery force multiply distance between plates for charge Q ,this work done per unit charge is known as electromotive force(EMF). In steady-state battery force is equal to electric force acting on charge Q within the battery hence EMF in a steady state is equal to potential difference between the plates. Positive charge Q came out from positive plate go through wire ,then came to negative plate and finally came to positive plate by battery force in this way steady-state current mentained in the circuit. Discharging of a battery when battery supply positive charge in the outer circuit and charging of a battery in which positive charge comes in from positive plate to the battery and came out through negative plate of the battery.
