Earthing transfers electrical energy directly to Earth through low-resistance wire. Connects non-current-carrying parts of equipment to ground. Prevents shock if insulation fails in electrical devices
Ground and neutral are circuit conductors used in AC electrical systems. Neutral conductor returns current to supply during normal operation. Ground conductor connects exposed metallic components to earth ground
Grounding connects electrical circuit parts to earth for safety. Electricity takes path of least resistance back to ground. Grounding electrodes must have maximum surface area contact with ground
Earth provides common return path for electric current. Chassis earth connects to metal frame or equipment case. Ground serves as reference point for voltage measurements
Power circuit notation comes from transistor circuit analysis. IEEE Standard 255-1963 defines 11 voltage symbol suffixes. Uppercase letters represent DC values, lowercase for AC
Ground has multiple names including Earth, Neutral, Common, Analog, Digital, and Instrument Ground. Earth Ground is a direct connection to earth, representing true zero volts. Common Ground serves as a circuit return path in many applications
