Yes, with a retroreflector. One form of a retroreflector is 3 mirrors all mutually perpendicular like the corner of a cube.
yes
A reverse polarity toggle switch does not inherently have power all the time; it depends on how it is wired in the circuit. When the switch is in the "on" position, it allows current to flow, which can reverse the polarity of the connected load. If the switch is off, there should be no power to the load. Always ensure to follow appropriate electrical safety standards when working with such switches.
Reversing polarity is not possible with an ac motor. Some do have wiring that will allow you to change rotation. The type and model of the motor can tell you if it is reversible.
It shows reverse readings
yes Electrode Positive is the same as Reverse Polarity
Reversing polarity ,changes the rotation of the device you are changing polarity on.
Reverse the polarity of the magnet.
i don't believe you can reverse the polarity on a fuse, they simply regulate the amperage of the circuit they protect,
If, by 'reverse polarity', you mean the accidental reversal of the line and neutral conductors at the socket outlet or receptacle, then the answer is no.
multiply by -1...
yes
i would never naturally assume any circuitry to be "reverse polarity" by default even if they are. since this can fry a lot of IC, and micro controllers. there are several options to adding a reverse polarity protection circuit to your project you can find three easy to implement circuits here: http://provideyourown.com/2012/reverse-polarity-protection-circuits/
Normal polarity.
we will have straight polarity and reverse polarity,we can produce the weld with good quality
no
nothing
it really doesnt
