1.Is filtered hot water a good conductor 2. is filtered water at normal temperature a good conductor 3.Is distilled water a good conductor?
1)yes 2)yes but not as good as before 3)no, there are no metal ions left in it to conduct.
Vacuum tube grid current changes in?
In normal operation there is no grid current, only a voltage.
What happens When a positively charged conductor is earthed?
As we know that in normal current flow, electrons passage is always from the negative to positive side , now in the case of earth it acts as a ground to the positive charge, and current flows from positive charge to the earth, which acts as a anode and as we know a passage of current occurs only if there is negatively charge electron flowing towards positively charged cathodes. So electrons may flow from earth neutralizing the positive charge.
How long ago did the current normal magnetic polarity begin?
780,000 years ago
Is cloth an insulator or conductor of elecricity?
Normal cloth made of typical natural fibers are good insulators. In fact, cloth was widely used to insulate electric wires for a while.
What cause current on the neutral line in a three phase?
Current on neutral in a multi phase system is caused by imbalance between the phases. Question: Are you talking about neutral or ground? The two are very different. Although neutral is grounded, it is expected to be a current carrying conductor, so current on neutral is normal, so to speak. Ground, on the other hand is a protective circuit that is not supposed to have any current on it at all.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
What is the process of bringing a negatively charged conductor in a contact with the earth resulting in the conductor discharging until it is completely neutral called?
The process is called grounding. Many devices need to be grounded, hence the U shaped pin on a devices that make contact with the ground in normal house wiring.
If a fuse becomes hot under normal load a probable cause is?
A fuse is nothing more than a conductor [wire] that is smaller than the conductor wire in circuit which the fuse is designed and intended to protect. The amount of current [measured in Ampheres (Amps)] creates some "resistance heating" in any conductor. The greater the current in relation to the size [and current carrying capacity] of the wire, the greater the heat generated. A fuse that runs warm or hot only indicates that it is carrying a lot of current, possibly near it's limit. When the current limit is reached, the fine wire in the fuse will melt [fuse], opening, or breaking, the circuit thus stopping the flow of current and protecting the conductor wire.
What is the speed of electricity?
The speed of an electric current is determined according to v = I/nAQ (average speed equals current divided by the number of charged particles moving, the cross-sectional area of the conductor and the charge of the particles). This basically means that a normal current e.g. the current in a house's wiring travels at about walking pace.
What is neutral to ground fault?
Neutral, by definition, is grounded at the distribution panel, and also at the distribution pole. That is how the hot to ground voltages are prevented from exceeding their normal voltage and encroaching on truly lethal voltages, such as 7.6kV in a typical US 13.2kV system, in a wye configuration.Note: and this is critical, do not depend on the fact that neutral is grounded and consider that it is the same as protective earth ground. It is not. Protective earth ground is a different wire.
When a person touches alive wire electrical current flows through his body how does this happen if the circuit is not complete?
Current may go to the ground, or another conductor. Also, your body may act as a capacitor, in other words, absorbing some current even if the circuit is not complete. Note that the normal household current is AC.
What is the meaning of short circuit conductor?
A short circuit conductor is just a conductor in an unexpected location, often with much lower resistance that is expected for the normal load.
Does Demi Lovato get grounded?
yes because at the end of the day shes just a normal teenager i'll tell you a secret demi got grounded on her 15th birthday she said"mom i dare you to ground me" and her mom said "ok demi your grounded"
What is rated normal current?
The rated current is the maximum current that can be drawn in normal continuous use, without any reduction in the lifetime of the device.
How do you connect grounding of i and c?
Grounding of I and C? to ground something is to have a wire that goes to a grounded connection the bare wire in a normal wire set.
What is the function of neutralization?
A CT is a current transformer, used to measure current flow in a conductor. Neutral is power return, usually grounded at the distribution panel. A neutral CT, then, is a device that measures the current flow in the neutral conductor. In a three phase star system, each phase returns current to neutral, but the three phases cancel each other out, resulting in effectively zero current in neutral. The neutral CT is used to detect an imbalance in the system, perhaps caused by a ground fault or by some failure in one of the phase loads. In a single phase, single ended system, there is current on neutral, so the value of a neutral CT is not so great. If you also had a hot CT, you could compare and detect imbalance between hot and neutral, which would be an indication of a ground fault. (Actually, a ground fault current interrupting device, also called a GFCI, usually compares current in hot and neutral simultaneously, because both conductors are wound together as the sensing transformer primary - any perceived current is a ground fault.) In a single phase, double ended system, such as the 120/240 split phase system used in the US, a current CT could indicate ground fault or a system imbalance but, usually, imbalance might be a normal situation as various loads are turned on and off.
