Yes, with a retroreflector. One form of a retroreflector is 3 mirrors all mutually perpendicular like the corner of a cube.
Incandescent, fluorescent, CFL, and flashlight bulbs will. LEDs won't.
yes you can
yes
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
Permanent magnet field motors. With a these motors, a permanent magnet is used to replace the field coil. DC power is connected via the brushes, to the armature only. Reversing the polarity, will cause the motor to reverse its direction of rotation. It is very common to use a switch to intentionally reverse to the polarity, to allow reversal of the motor if desired.
What can reverse magnetic 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
we will have straight polarity and reverse polarity,we can produce the weld with good quality
Normal polarity.
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/
Separate strictly the words phase shift and reverse polarity. Scroll down to related links and look at "Phase shift". Scroll down to related links and look at "Reverse polarity".
