In automobiles it means that the frame is used as the common ground return for all electrical circuits. One side of the accessory is connected to the +12 supply and the other side of the power input is connected to the frame where the negative side of the battery is connected.
The preferred method now is to use a separate ground wire for each group of electrical devices rather than connecting to the frame of the vehicle. It is more reliable and in some cases easier to troubleshoot when problems arise. It also prevents "ground loops" where one group of devices interfere with another because of currents flowing through a common ground path. By using a separate ground wire for each, common paths can be eliminated.

The components are connected in series (not parallel).
What is the difference between kilo volt and kilo watt?
A "kilo" means 1000. So a kilowatt is a thousand watts. The same applies to voltage. A kilovolt is 1000 volts. Wattage is the measurement of "electrical power". Voltage is the measurement of "electrical potential" See "Ohms Laws" for more explanation of electrical terms.'
How do electronics work?
There are a number of components in any circuit and their job is to restrict the flow of electrons and reduce the current or voltage flowing by converting electrical energy to heat. In other terms, electronics control the electrical circuit. Electric charge is nothing but the flow of electrons from one object to another. The working of the microwave is the example of how electronics work. In a microwave, electricity provides the power that generates high-energy waves that cook your food and electronics controls the electrical circuit that does the cooking.
What is meaning of lv leads hv with 30 degree?
"LV leads HV with 30 degrees" typically refers to the phase relationship between low voltage (LV) and high voltage (HV) electrical systems. In this context, it indicates that the voltage of the LV system is leading the HV system by 30 degrees in terms of phase angle. This phase difference is important in power systems to ensure proper synchronization and efficient operation of electrical equipment. Overall, it highlights the timing difference between the two voltage levels in an electrical circuit.
What is the difference between earthing and grounding and how do they relate to each other?
Earthing and grounding are terms used interchangeably to describe the process of connecting electrical systems to the earth. Earthing specifically refers to the connection of electrical circuits to the ground to prevent electrical shocks and ensure safety. Grounding, on the other hand, is a broader term that encompasses both the physical connection to the earth and the process of neutralizing electrical currents. In essence, earthing is a specific type of grounding that focuses on safety measures in electrical systems.
What is the difference between grounding and earthing?
Grounding and earthing are terms used interchangeably to describe the process of connecting an electrical system to the ground to prevent electrical shock and protect against power surges. Grounding typically refers to the practice of connecting electrical circuits to the earth, while earthing is more commonly used in European countries to describe the same process. Both grounding and earthing serve the same purpose of providing a safe path for electrical currents to flow into the ground, reducing the risk of electrical hazards.
