The two basic types of communications systems are: Analog communication systems, and Digital communication systems. An analog communication is a system in which the information signal is transmitted and received in an analog form means a continuously varying signal such as sine wave. Here, both the information and the carrier are analog signals. In digital

The ideal gas equation establishes the relationship among the pressure exerted by a certain number of moles of a gas, its temperature and the volume occupied by it. But the pressure exerted by a mixture of gases present in a container was studied by Dalton. Dalton’s law states that “the total pressure exerted by a

The ohm’s law can be derived from the equation J= σE. Consider a segment of wire of length l and cross sectional area A as shown in figure When a potential difference Vis applied across the wire, a net electric field is created in the wire which constitutes the current in the wire. For simplicity, we

When a conductor moves in a magnetic field, the direction of motion of the conductor, the field and the induced current are given by Fleming’s right hand rule and is as follows: The thumb, index finger and middle finger of right hand are stretched out in mutually perpendicular directions. If the index finger points the
