Electric current flowing through a conductor I = nAqVd
where A = cross-sectional area of the conductor, n= number of conduction electrons per unit volume, q is the charge of an electron and Vd is the drift velocity.

Capacitors are used in the electrical circuits where appliances need more. And when it is disconnected from its charging circuit, it can dissipate that stored energy, so it can be used like a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. In analog filter networks, they smooth the output of power supplies. ... In electric power transmission systems they stabilize voltage and power flow.

Coulomb’s law states that Force exerted between two point charges:
- Is inversely proportional to square of the distance between these charges and
- Is directly proportional to product of magnitude of the two charges
- Acts along the line joining the two point charges.
Here ε0 = 8.854 x 10-12 C2 N-1 m-2is called permittivityof free space.

The common thing among the three states of matter is-they consist of tiny, small particles. They have a specific mass and can take up space. There is a volume in these three states. In these three states ‘atoms have the strength of attractions between them.

Three basic properties of photons are given as below :
(i) Photons are quanta or discrete carriers of energy.
(ii) Energy of a photon is proportional to the frequency of light.
(iii) The photon gives all its energy to the electron with which it interacts.

The mirage is caused by the total internal reflection of light at layers of air of different densities.In a desert, the sand is very hot during day time and a result the layer of air in contact with it gets heated up and becomes lighter. The lighter air rises up and the denser air from above comes down.
As a result, the successive upper layers are denser than those below them. A ray of light coming from a distant object, like the top a tree, gets refracted from a denser to a rarer medium. Consequently the refracted ray bends away from the normal until at a particular layer, the light is incident at an angle greater than the critical angle. At this stage the incident ray suffers total internal reflection and is reflected upwards. When this reflected beam of light enters the eyes of the observer, it appears as if an inverted image of the tree is seen and the sand looks like a pool of water.

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.

Alloys like constantan and manganin are used to make standard resistance coils because:
1. They have a very high value of resistivity.
2. They have a very small temperature coefficient of resistivity. Thus, their value of resistivity does not change even for very high values of temperature.
3. They are least affected by atmospheric conditions like, temperature, moisture, air, etc..
4. The contact potential of alloys with copper is very small
