Where is the positive and negative terminal of the overhead wire for local trains?
One terminal is the overhead wire, and the other terminal is the track, which is grounded.
What is the difference between a floating output signal generator and a grounded output signal generator?
A signal generator can be used to function in two ways. In high frequencies, one of output probes of any generator (negative probe) will be grounded automatically, hence it has to be connected with grounded parts of other elements not to create a short circuit problem. But, in the case of floating type (f<100 Hz, generally) probes of the signal generator is not grounded.
Why does a live wire shock the ground or trip the power when it comes in contact with the ground we walk on?
Because that completes a circuit. The live wire is one terminal of a high voltage transformer at the substation. The other terminal is grounded to earth ground, and earth is conductive.
Why positive terminal grounded to make the supply negative?
A DC circuit, of course, does not need to be grounded. It just needs a path from the negative to the positive (the actual flow of electrons). One can often simplify the wiring by using a common "ground" bus which might include a car's chassis for example. If the negative terminal is grounded, then everything that is not "ground" would be positive. Likewise, if the positive terminal is grounded, then everything that is not "ground" is negative. Since you are looking at return paths... you could potentially have 2 batteries, one that is negative grounded and one that is positive grounded. Consider two 12 volt batteries: +12V(a) -- (-12)V(b) -- GROUND -- (+12V)(c) -- (-12V)(d) If you connect (d) to either (b),(c), or Ground, one would have a 12V difference with (d) being negative. If you connect (a) to either (b), (c), or Ground, then one would have a 12V difference with (a) being positive. If you connect (a) to (d) then one would have a 24V difference with (a) still positive and (d) still being negative. One note... When Steel is given a negative potential (charge), it corrodes less than when it is given a positive potential (charge). This is the reason why negative ground is almost universally used on automobiles.
How to wire a 12 volt coil?
To wire a 12-volt coil, connect one terminal to the ignition switch's "hot" terminal and the other terminal to the distributor in the ignition system. Make sure the coil is grounded properly for it to work effectively in the circuit. Refer to the manufacturer's instructions or a wiring diagram for your specific vehicle to ensure proper installation.
Why the current not flowing through the wire when one end is connected to the positive terminal and the other end is let open why the positive potential does not affect the electrons in the wire?
since it is not grounded ,it does not accept the flow of current
What will cause a star-delta starter to trip a generator when started in star?
One or more reasons may be:The load of the motor (HP) is too large for the output of the generator.The generator's breaker is sized too small for the generator's full load output.Short circuit in the motor.Megger the motor first to see that the windings have not grounded-out. Windings to ground should be above 5 meg.
Where can one purchase a generator cord?
A generator cord can be purchased at one's local hardware store, as well as local generator distributors. One can find generator cords on eBay and Amazon as well.
What consequences does a person who is grounded for life have?
Although it is common to hear the term that one is being grounded for doing something wrong, it is usually unheard of that one would be grounded for life. There was an American sitcom television show back in 2001 that was titled "Grounded for Life".
What is the wiring for a regulator on a 1977 harley Davidson sportster?
a wire goes from the a terminal from generator to the g on reg.the f from gen goes to f on reg .one wire from positive batt to b on reg.
How do you make generator output voltage stable?
Inside the generators junction box there will be termination points that the generator coils terminate on. On the inside of the lid of the junction box there should be a diagram for different connections allowed for that generator. By moving jumpers around across these terminals a variety of voltages can be obtained.
How do you use a single terminal car horn on a two terminal electrical wiring system?
On a vehicle, the return path to the battery is through the vehicle's framework. The negative terminal of the battery is connected to the frame of the vehicle. The reason there is only one terminal on the horn is that, that is all that is needed to make the horn operate. Applying the positive side of the battery to the single terminal which is connected to the horn's coil will make it operate. When the horn is bolted to the vehicle this completes the circuit back to the negative terminal of the battery. Apply the 12VDC to the horn by pressing on the horn button which closes the circuit and the horn activates. A horn with only one terminal has its coil grounded internally within the horn. A horn with two terminals has the coil isolated from the ground. On a two terminal horn there needs to be a wire installed to the frame on one of the terminals to make the horn operate.
