Calculating Transformer and Battery Specs While making an inverter, two calculations must be broadly taken into account, viz. the transformer and the battery ratings. 1) The transformer must be approximately rated twice the maximum load that is expected to be used with the inverter. For example if the intended load is 200 watts, then the … Read more
PCB Etching Currently used for print circuit board etching of solvents are iron (Ferric Chloride), cupric chloride (Cupric Chloride), alkaline ammonia (Alkaline Ammonia), sulfuric acid hydrogen peroxide (Sulfuric Acid + Hydrogen Peroxide) etching fluid, ammonium persulfate, sulfuric acid – chromic acid etching solution. Like the PCB manufacturing in Fusion PCB of Seeed. Etching liquid are … Read more
Information technology There are four primary elements for information technology as a whole: information security, database and network management, computer technical support, and business software development. Information technology covers many different areas, including software solutions and hardware that allow organizations and companies to organize, gather, and evaluate data. Ultimately, the analysis of this data helps … Read more
Antenna An antenna is an electrical device which converts electric currents into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter applies an oscillating radio frequency electric current to the antenna’s terminals, and the antenna radiates the energy from the current as electromagnetic … Read more
PARACETAMOL Is an anti pain relieve and fever reducer. The exact mechanism is not known.Paracetamol is used to treat many conditions of headache,muscle aches, arthritis, backache, toothache, and fevers. It relieves pain in mild arthritis but has no effect on the underlying inflammation and swelling of the joint. Paracetamol may also be used for other … Read more
Replace TDA2030 with TDA2050 TDA2050, TDA2050H The TDA 2050 is a monolithic integrated circuit in Pentawatt package, intended for use as an audio class AB audio amplifier. Thanks to its high power capability the TDA2050 is able to provide up to 35W true rms power into 4 ohm load @ THD = 10%, VS = … Read more

Difference between normal diode and Solar PV diode? In solar PV panel, P-N junction diode is used as solar PV cell which absorbs the light and convert light into electricity. But normal diode can not absorbs the light. Crystalline solar cells and photodiodes are basically the similar as p-n diodes. Nevertheless … Read more
Cell Membrane • The cytoplasm of a cell is surrounded by a cell membrane or plasma membrane. • All cells, have a membrane that envelops the cell, separates its interior from its environment, regulates what moves in and out (selectively permeable), and maintains the electric potential of the cell • Inside the membrane, a … Read more
Drop high voltage to low voltage using a silicon rectifier diode A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction. Drop high voltage to low voltage using a silicon rectifier … Read more
