***IMPORTANT NOTICE***
---------------------
1. Electrical deals with mostly AC signals.
Electronics deals with mostly DC signals.
2. Electrical deals with mostly ANALOG signals.
Electronics deals with mostly DIGITAL signals.
3. Electrical devices are mostly TRANSFORMERS, MOTORS,
GENERATORS, STARTERS etc...
Electronic devices are mostly DIODES, TRANSISTORS,
ICs(i.e, SEMICONDUCTOR DEVICES), etc...
4. SOURCES and LOADS belongs to ELECTRICAL
SIGNAL PROCESSING DEVICES belongs to ELECTRONICS
5. RESISTOR, CAPACITOR AND INDUCTOR belongs to which
category?
6. What is the difference between AC loads and DC loads?
7. Why AC motors, AC bulbs etc... are donot operated by
DC signals? and
Why DC motors, DC bulbs etc... are donot operated by
AC signals?

1 “earthing” for bonding of equipment and circuits to common plant earth electrode potential, 2 “protective earthing (PE)” when this bonding is required for personal safety provisions 3 “grounding” for interference suppressing bonding of screens, sys-tems with ground level 4. low-impedance earthing ? 5.primary earthing system and secondary earthing system what is that? 6.earthing electrode or mesh net earthing electrode ? very confusing , simple but very informative help required ? i will be very very thankful to you guys.

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
