Grounding terminals are used to connect the electrical equipment or wiring system to the Earth. It's purpose is to reduce the risk of electrical shock in the event of a fault current. In most homes, the wiring system is permanently grounded to a metal pipe that connects to an underground water-supply system or to a metal rod that has been driven into the ground.

What does a positive connection between two parts mean?
Simple question complex answer - if the connection is electrical or electronic then the connection allows a flow of electricity from positive to negative. If the connection is engineering then the connection is because the connection is securely closed and locked
Define a direct short?
When there is a connection across both the positive and negative voltages.
How do you check the headlamp resistance in th earth connection?
The resistance (ohms) between the headlamp "earth" connection and the vehicle battery NEGATIVE connection should be near zero. Although zero ohms is technically not possible in anything short of a superconductor, the resistance should not be much more than 1. If the resistance is much more than that, you should clean rust/corrosion from connectors and use some kind of rust inhibiting/conductive material to improve the conductive properties of the circuit. The above is true, but not easy. If in doubt of any ground connection in a car, just run another ground wire from the item to somewhere you know is a good ground (car frame, ground buss, negative battery cable, etc)
What is negative clipper?
a clipper that is negative
When was Negative pressure ventilator created?
Negative pressure ventilator was created in 1928.
A condition NOT regulated by a negative feedback loop would be?
body temp
Is blood regulated by negative or positive feedback?
negative feedback via baroreceptors in the carotid artery and aortic arch
Are contractions in the uterus a process regulated by negative or positive feedback?
Uterine contractions are one of the few physiologic process regulated by positive feedback.
Are high beams positive or negative on 1997 crown Victoria?
They need both a positive connection and a negative connection to function.
what direction does negative feedback mechanism drive the factor being regulated?
in the oppesite direction ;)
How is the cell cycle monitored?
It is regulated by various enzymes and negative feed-back mechanisms.
When welding with DCEN the electrode is positive and the work is negative?
DCEN means Direct Current Electrode Negative. Hook the welding cable to the Positive connection (+) on the machine, the ground cable to the Negative connection (-) Electricity travels from Negative pole to Positive pole.
What is the different between series and parallel connection?
In parallel connection all the positive terminals are connected with positive of the source and all the negative terminals are connected to negative of the source. Whereas in series connection one positive terminal is connected to the negative of another, like wise it goes on and finally the positive end is connected to the negative of the source.
Does static electricity have negative electrons?
yes it contains both positive and negative
Serial connection definition?
This connection goes from negative 2 positive which raises the voltage. Thanks!! o.o
Is blood pressure regulated by positive or negative feedback?
Aldosterone is both responsible for absorption of sodium and excretion of potassium. If it is regulated by the level of potassium in blood, then we have negative feedback as high levels of aldosterone causes a decrease in potassium level in blood. If it is regulated by the level of sodium in blood, the story is just the opposite and we have positive feedback. -my own conclusion from several researches-
