What is the definition of frame grounding using electrical terms?

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.

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 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.'
What is the difference between a transmission grid and an electricity grid?
The terms transmission grid and electrical grid are somewhat interchangeable. The electrical grid, or power grid, is the network used to get electric power from where it is generated to all the places that use it. The one difference might be that a transmission line or grid might be thought of as the network of high voltage long distance lines. These are used to move large amounts of power with minimal loss through the use of extremely high voltages. These long distance lines connect generation facilities with substations, and it is at the substation that the voltages are stepped down, and that power is then put on the electrical grid.
