How many galleons of water can be pumped through an inch and a quarter copper pipe?
As many as could flow through before eroding the piping to the point of no more flowing through and it simply spewing about.
How can you detect a direct current flowing thugh a wire?
you need to test it with a multi meter, set on the right settings. if you knew the voltage you could get an appropriate light bulb to suit the voltage and put that across the wire to test if there is current.
What type of current flows through an electric current?
Current is the flow of electrons. This could be DC (direct current like what you find in a battery) or AC (alternating current, what you find in a regular plug for example). Current is measured in Amperes or amps. And if you have the unfortunate chance of being shocked, amps are what could actually harm you or kill you.
Which effect of current does the fuse wire in electric circuits utilize?
The heating effect is used. Normally the current flows through the fuse without undue heating. But if too much current passes through, the fuse will heat and melt, thus stopping the current which could cause a fire if it was not stopped.
Could a magnetic field be electrons flowing through power lines?
A magnetic field is caused by flowing currents, but the field lines are not directly related to the flow of electrons or other charged particles. They are simply an abstraction that tells you where the magnetic attraction is strongest, and in what direction it goes.
How moeller's overload relay works?
Moeller's overload relay works by monitoring the current flowing through a motor. If the current exceeds a set value for a period of time, the relay will trip and disconnect power to the motor, protecting it from damage due to overheating. This helps prevent the motor from drawing too much current for an extended period, which could be harmful.
How transformer output connections get burn?
Poor connections could result in arcing; the transformer could be overloaded as well, resulting in more current flowing through them than designed.
What is The rate or speed of water flowing through the pipe that is like the rate of the electricity flowing through a conductor measured in?
gallons per minute could be considered analogous to amperes
What could happen if the water stopped flowing through a nuclear reactor?
overheatingpossibly meltdown
What is the current flowing through a 200 watt resistor that has a rating of 21 ohms?
The current can't be calculated from the information given in the question.The power rating of a resistor is the maximum power it can dissipate before it overheatsand its resistance possibly changes permanently. The power rating is not the amount ofpower it always dissipates.So, all we really know about the resistor in the question is that its resistance is 21 ohms.And all we can say about the current through it is:Current through the resistor = (voltage between the ends of the resistor) divided by (21).
Why do you short voltage source and open current source while using superposition theorem?
You short a voltage source when doing this analysis because you do not know how much current will flow through the voltage source - consider it an undefined value. For the same reason, you open a current source since you know how much current will be flowing through it. This is a simple explanation; I'm sure a more exhaustive, technical one could be made if this is not sufficient.
Why would a fuse blow in a 12 volt negative ground radio?
The fuse would most likely blow as a result of current flowing through it in excess of the current that the fuse is rated for. In general, there are two things that could cause this: Most likely, either the fuse installed was rated for less current than the radio uses in normal operation, or else a fault in the radio caused more current than usual to flow through the fuse.
Do Vegetables have electric current?
I've never tried it and I could be wrong but I believe you could pass an electric current through a vegetable, especially one with a high water content. Similar to how you can pass an electric current through a person.
What are the reasons of earthing?
Safety!!!!Although the neutral wire is also connected to ground/earth, it has current flowing through it and can thus easily have 20VAC (sometimes more) on it at the outlet. If this were connected to the metal housing of appliances it could cause a significant electrical shock to the user.The ground/earth wire is never supposed to have current flowing, so it will always have 0V on it at the outlet and can thus be wired to the metal housing of appliances without risking electrical shock to the user.

Why ammeter use fuses and volt meter do not?
An ammeter measures current THROUGH a circuit, a voltmeter measures current ACROSS a circuit. The ammeter is connected to a power source in series, essentially actually becoming part of the circuit. The current is flowing directly through the ammeter as if there were a wire in its place. If there is a surge from a substantial power source, the ammeter would be destroyed and the user could be severely injured. The fuse will "blow" if its "load" is exceeded breaking the circuit. A volt meter is connected to a power source in parallel because it has an extremely high resistance and little to no current would get through. You don't need a fuse because the current doesn't flow through it openly.
How do you make 110 amp convert to 12 volt?
Ohm's Law states Volts = Current x Resistance. Your question makes no sense. Volts measure "potential" whereas the current can be thought of as moving the potential in the form of electrons through a wire and eventually a load. An analogy that may help you form your question is a vat of water. Imagine that the volume of water is potential energy. If you had a valve at the bottom of the vat and turned in on slightly, the water flowing out could be considered to be current. You could use it to do work such as run a water wheel. Then the potential (water) ran out you could relate that to current flow. The amount the valve was open could be thought of as the resistance to the flow of current. Hope this helps.
