Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 32: Electric Current in Conductors

Drift Velocity

Drift velocity is an average velocity achieved by charged elements, such as electrons, in a substance due to an electric field. Relating an electric field adds to this unplanned motion a small net flow in a particular direction. This is known as the drift.

Ohm’s Law

Ohm’s law defines that the current passing through a conductor between two points is directly proportional to the voltage through the two points.

Temperature Dependence of Resistivity

To eliminate the influence of size from resistance, resistivity is used. This is a physical property that does not depend on size. Resistivity is affected by temperature – for most resources, the resistivity rises with temperature. The ease with which a substance conducts heat is calculated by thermal conductivity.

Kirchoff’s Law

Kirchhoff’s current law defines that the current passing into a node must be equivalent to the current flowing out of it. This is the significance of charge conservation.

Kirchhoff’s voltage law defines that the sum of all voltages around any locked loop in a circuit must be equivalent to zero.

Atmospheric Electricity

Atmospheric electricity is the theory of electrical charges that are located in the atmosphere of the Earth. The movement of charge between the surface of the Earth, the atmosphere, and the ionosphere are called the global atmospheric electrical circuit.

Energy Transfer in an Electric Current

If we supply electric current with a source of energy and a whole circuit, then the electrons will all move in the identical general direction through the wire. This measure of electrons through a conductor is electric current. We can say that an electric circuit is an enclosed system that transmits electrical energy.

Ammeter and Voltmeter

A voltmeter is a tool used for calculating electrical potential transformation between two points in an electric circuit. An ammeter is a calculating instrument used to calculate the electric current in a circuit.
