Why is the earthed side of a circuit negatively-charged ie attract positively-charged ions?
There's no reason that the circuit must be configured that way. There are many
circuits, devices, and applications in which the positive side is earthed.
For example ... and for some reason that I still don't know after a lifetime in the
telecommunications industry ... most telephone systems are powered with negative
DC power plants, that is, with huge DC power plants and battery banks whose
positive sides are earthed.
What else can I help you with?
Electric fittings are earthed so that?
current may pass to the earth in case of short circuit without any harm.
Why put earthed strip between a circuit and the circuit board?
An earthed strip is a low resistance strip. as we know that a current always flows along a path which is having the least resistance.Whenever a fault current flows through the circuit and a possiblity is there that it may damage the ckt & ckt board the earth strip allows the fault current to flow through it and ground it. thereby preventing the damage.
When was Earthed to the Ground created?
Earthed to the Ground was created in 1984-05.
Why zero sequence current cannot flow through a star connected machine unless the neutral is grounded?
If the neutral point is not earthed than the zero sequence current will not have any return path.It will be an open circuit for the zero sequence circuit.
What is common collector bipolar junction?
A circuit in which the input signal is applied to its base and the collector is earthed (grounded) is known as common collector configuration of BJT (BiPolar Junction Transistor)
Why are hair dryers not earthed?
Things that aren't grounded, like hair dryers, are double insulated. If the hair dryer gets a short circuit, the two layers of insulation will protect you. Hair dryers also have a ground-fault circuit interrupter plug that protects you if you drop the appliance in water.
Why must a fuse always be connected in a non-earthed conductor?
It is the ungrounded conductor that carries the load current. It is that conductor that needs to be protected should a fault current occur. That is what the fuse in that circuit does.
Can insulator be earthed?
yes
Why live and neutral wire essential for proper working of electrical circuit?
Two wires are always needed to supply electrical equipment so that the current has a complete circuit to flow in. One of the wires is earthed at the supply transformer, that one is called the neutral, and the other one is the live.
Does a vacuum cleaner need to be earthed?
no
Are Hyundai getz positive earthed?
no
Should front wheel bearings be earthed?
Front wheel bearings in a car should be well greased but have never heard of them needing to be earthed.
