Chapter-04 Electromagnetic Induction by Thayalan Kuppusamy (2017) Edition : 2/e

According to Faraday, current can be produced in a closed conductor, whenever there is a change in the magnetic flux passing through the conductor. The current exists only as long as the change takes place. The current produced in the conductor in this way is called an induced current. The electromotive force (emf) that produces the current is called an indu... [More]

Membranes are asymmetric sheet like enclosed structures with an inside and an outside. These sheet like structures are thermodynamically stable but electrically and metabolically active. By forming closed compartments around cellular protoplasm, membranes separate one cell from another, thus permitting cellular individuality. Membranes act as barrier, with s... [More]

The association of electricity with medical sciences dates back to the 18th century when Galvani demonstrated that most of physiological processes were accompanied with electrical changes. The electric field generated by the action of nerve and muscle cells constitute bioelectric signal. This chapter discusses various aspects of the electrical signals which ... [More]

Chapter-05 Transformer and Rectifier by Thayalan Kuppusamy (2017) Edition : 2/e

A transformer is an electrical device, which can convert electrical energy from one coil to another coil. It is used to convert low alternating voltage into high alternating voltage and vice versa. The transformer is working on the principle of mutual induction. The transformer basically consists of two coils, namely primary and secondary coils. These insula... [More]

Dynamics of blood flow through body was investigated by French physicist and physician J.L.M Poiseuille in 1799. As the blood vessels are not rigid and fluid flowing through them is non-newtonian the Poiseuille’s law does not apply as such to flow of blood through vascular system. This chapter highlights principles of flow dynamics in human body. Differences... [More]
