steady current through a material is directly proportional to the voltage across the material divided by the electrical resistance of the material. The ohm (R)‚ a unit of electrical resistance‚ is equal to that of a conductor in which a current (I) of one amp is produced by a potential of one volt (V) across its terminals. These fundamental relationships represent the true beginning of electrical circuit analysis. Current flows in an electric circuit in accordance with several definite laws. The basic

actuates an arm inside and closes the circuit. Relays are used as switches to control larger circuits with more power. Since a relay is able to control an output circuit of higher power than the input circuit‚ it can be considered to be a form of an electrical amplifier. When using a relay in a dc current‚ diodes are put in across the coil to dissipate energy from the collapsing magnetic field at deactivation‚ which would cause a spike in voltage and damage components if not there.

Case Study No.1 Alma Electronics: I’ll Dream of You Introduction In 1979‚ Mr. Andy Mallari opened a small shop selling transistor radios which was located at one corner (Gen. Luna St.) of the entire stretch of Burgos Avenue‚ the main thoroughfare of Cabanatuan City. After eleven years‚ he was able to save money for the expansion of his business along Del Pilar Street due to increasing demand for electronic parts used in the assembly and maintenance of radios‚ tape recorders‚ amplifiers‚ and

electric heater and more. Heating effect of electric current are below (i) Electric iron: In an iron the upper part is grooved. In this groove a coil is placed. Mica as an insulator is placed between the metal part and the coil‚ so that there is no electrical connection between them. Mica is a bad conductor of electricity but it is a good conductor of heat. Due to the flow of current through the coil it becomes heated and the heat transferred to the metal part through mica. Finally the metal part becomes

After High school‚ when I got a chance to enter the Department of Electrical & Electronic Engineering at the XXX‚ I was more than excited and did not think twice to grab it. It is noteworthy to mention that XXX is well reputed and the only international university in the country. The well designed course curriculum along with associated lab works of XXX drove me towards depth study of all basic modules of electrical engineering. The practical essence of theories always inspired
