discuss the current and voltage effect on the wiring circuit with earthing and without earthing
Depends on if the circuit is using an earthing safety ground in a building or the earthing ground used on the Distribution system supplying your home or building. In a building the earthing (ground conductor in the USA) serves only a safety ground used to protect against inadvertent current flow to ground through a faulty appliance or accidental fault or short circuit. On the Distribution system using a 4 wire WYE system, the neutral wire is connected directly to earth at numerous locations along the system. This causes about 1/3 of the current flow that would typically flow on the neutral conductor to flow through the earth back to the source. Hope this helps, Newton1Law
did you get it aligned? It could be out and causing the tires to scrub
Discuss the effect of not paying attention in class?
Unless there is a ground fault in the circuit there is no difference. The purpose of the ground fault wire is to keep the circuit and chassis at a safe voltage even if there is a fault in it.
