Primary Cells

Primary cells produce electricity by the virtue of chemical reaction. In primary cells,the reaction occurs only in one direction, and cannot be reversed. As a result these cells become deadover a period of time.
Primary cells cannot be recharged/reused.
Typical primary cells are, Daniell cell, Dry cell, and Mercury cell.

In electrostatic free charges is a good conductor which reside only on the surface . So, the free charge inside the conductor is zero (the charges are of the same nature and distributed uniformly and hence cancel each other effect).

Electric field is zero in that point because the sum of electric field vector have same intensity and direction but are opposite that point is halfway between two like charges

Ayush Vishwakarma?? 5 years, 2 months ago

Electric field at centre is zero because the sum of all the vectors of charges at the centre has same magnitude but opposite dirn so this is happened.

Ayush Vishwakarma?? 5 years, 2 months ago

E= Kq/r^2 then at the centre radius is is constant means (R).and at the centre value of r=0 so E field is zero.

Is resistivity of insulator independent of temperature because of high energy gap ?

Posted by Ajay Krishna 5 years, 2 months ago

CBSE > Class 12 > Physics

1 answers

Khushi....? ??‍? 5 years, 2 months ago

In the case of insulators the energy gap between the valence band and the conduction band is around 5eV . Hence till the temperature rises sufficiently to impart enough energy to the electrons to be able to move into the conduction band - there should be no or negligible effect on the resistivity of an insulator.

ANSWER

At a point due to a point charge, the values of electric field intensity and potential are 32 NC-1 and 16 JC-1, respectively. Calculate the (a) magnitude of the charge, and (b) distance of the charge from the point of observation. [IITJEE/ADV]

Resistance increases, in case of conductor, with increase in temperature and decreases, in case of insulator, due to increase in temperature.

In case of conductor, the valance band and conduction band overlap with each other. So, there are excess electrons in the conduction band of a conductor. When you increase the temperature, more electrons will go to the conduction band from valance band by absorbing the energy. So, the conduction band becomes crowded and there will be more collision between the electrons which increases the resistance. So, with increase in temperature, the resistance of conductor increases.

But in case of insulator, there is a large energy gap between the two bands. So, if the temperature rise is high, the electrons will go to the upper band. But since it is not crowded due to less number of electrons, so the conductance will increase due to availability of free electrons in the conduction band. So, the resistance decreases with increase in temperature in insulator.

Electric potential difference between two points in an Electric field is defined as the amount of work done in moving unit positive charge from one point to another point against the electric force.

In other words, Potential difference is simply the difference of scalar potentials between two points or anything you consider.

If 10^9 electrons move out of a body to another body every second how much time is required to get a total charge of one coulomb on the other body??(plz understand me.)

Posted by Ayush Vishwakarma?? 5 years, 3 months ago

CBSE > Class 12 > Physics

1 answers

Gaurav Seth 5 years, 3 months ago

Charge of one electron= 1.6×10^-19 C

Charge of 10^9 electrons = 1.6×10^-19 C × 10^9

= 1.6×10^-10 C

We can say,1.6×10^−10 C of charge move out of the body to another body every second.

The time required to get a total charge of

1C = 1sec/1.6×10^-10 C

= 6.25×10^9 / 365×24×3600

= 197.8 years or approximately 198 years.
