Magsisimula po tayo sa “What” –referring to electronics in general.
Leak, leaked, or leaking.
In electronics, leakage may refer to a gradual loss of energy from a charged capacitor. It is primarily caused by electronic devices attached to the capacitors, such as transistors or diodes, which conduct a small amount of current even when they are turned off. Even though this off current is an order of magnitude less than the current through the device when it is on, the current still slowly discharges the capacitor.
In semiconductor devices, leakage is a quantum phenomenon where mobile charge carriers (electrons or holes) tunnel through an insulating region. Leakage increases exponentially as the thickness of the insulating region decreases.
Leaking – sa madaling salita ay “may tagas”
Ground, or grounded.
In electronics, serve as return paths for signals and power within equipment, and on the signal interconnections between equipment. a single return that acts as a reference for all signals. Power and signal grounds often get connected, usually through the metal case of the equipment.
Usually in electronics, ground is just a name we give to a certain point in the circuit. In a circuit with one battery (with a positive and a negative terminal), we usually refer to the negative terminal as ground. Ngunit sa ibang mga halimbawang schematic diagrams na may kaugnayan sa ating pag gawa tulad na lang nang isang amplifier section na may mga kuneksyong patungong positive, negative, at mismo ng ground. Ang tanong papaanong nangyayari yun?
Halimbawa na lang ng isang simpleng schematic diagram na ito,
sa larawang ito ipinahiwatig na ang ground ay isang kuneksyon na napapagitna sa isang positive at negative supply. If the voltage measured between the negative and the positive terminal, voltage drop is 9 volts, this means the ground would be at 4.5 volts. But in this case, we would call the positive terminal as 4.5 volts and the negative terminal -4.5 volts. And the ground terminal we would refer to as 0 volt or neutral.
Huwag pong malito kung sasabihin kong meron tayong voltage drop na dalawang tig 4.5 volts at meron ding 9 volts. Tandaan na ang voltage drop po ay di parating naka punto lang sa gitna ng positive at zero potential node/junction sa isang circuit, kundi ito ay nakadepende sa kung saan ang reference point na pinagkukunan ng measurement ng dalawang punto irregardless of signs (positive and negative).
Short, or short circuit
A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or a very low electrical impedance. Bakit sinasabing impedance in general? Maaari po ng bumatay dito sa single post na ito -- >http://gsmsandwich.com.ph/threads/basic-capacitor-troubleshooting.505970/#post-4066705
May isa pang halimbawa (dito po magsisimula ang "When")
Kung sakaling magsasagawa tayo ng multi-tester test sa supply ng mobile phone to determine leakage,shorted and grounded:
pag ang C1 ang ma-short, maaring sabihing shorted oh grounded ang capacitor/mainboard, subalit pang ang C2 masoshort di maaring sabihing grounded subalit shorted sa ibang banda. Gayundin po ang pag-uusapan kung ito ay may leakage.
Sana po ay may kunting makuha na punto sa paksa.
