The cells used for electrolysis are called electrolytic cells while those used for generation of electrical energy from chemical reactions are called galvanic or voltaic cells. The practical application of a galvanic cell is Daniel cell. The electrode where oxidation occurs is called anode and the electrode where reduction occurs is called cathode. John Daniell

The chemical reactions in which both oxidation and reduction occur simultaneously are called redox reaction. Oxidation is the process where electrons are lost from a species and reduction is the process where electrons are gained by a species. On the other hand, the species which reduces other species and itself undergoes oxidation by donating electrons

Sodium-potassium pumps, also known as Na+/K+-ATPases, are integral membrane proteins responsible for maintaining the electrochemical gradient across cell membranes. This gradient is vital for numerous cellular functions, including nerve signal transmission, muscle contraction, and nutrient uptake. Structure of Sodium-Potassium Pumps At the structural level, sodium-potassium pumps consist of several subunits, including alpha and beta subunits.

A cell is a device for the conversion of electrical energy into chemical change or vice versa. It is a system containing two metallic electrodes, dipped into the same or different electrolytes, connected by an external metallic conductor. Types of cells The cells are classified into two types: Electrolytic cells. Electrochemical cells. Electrolytic cells These

Electrochemistry is a branch of physical chemistry that deals with the relationship between electrical energy and chemical energy. It is the study of processes involved in the inter-conversion of electrical energy and chemical energy. Conductors are substances, which allow the electric current to pass through them. Eg., metals, graphite, fused salts, aqueous solutions of acids

An AM wave expression consists of carrier and two sidebands. The carrier component of the modulated wave has the same amplitude as the unmodulated carrier. The AM modulated wave contains extra power in the two sideband components. The amplitude of the sidebands depends on the modulation index ‘ma‘. Therefore the total power in the modulated

The foundation of all experimental science and technology is measurement. The result obtained from any measurement will contain some uncertainty. Such an uncertainty is termed error. Any calculation made using the measured values will also have an error. It is not possible to make exact measurements in an experiment. In measurements, two different terms, accuracy

The concept of length in physics is related to the concept of distance in everyday life. Length is defined as the distance between any two points in space. The SI unit of length is metre. The objects of our interest vary widely in sizes. For example, large objects like the galaxy, stars, Sun, Earth, Moon
