What is a light sensitive switch?
this is due the action of the photo transducer.when the light falls on the swtich, suddenly the resistance decreases.and the switch is closed.
How do you switch poles in electromagnetic field?
You get a battery, switch, nail and copper wire. You connect one end of the battery to the switch and the other end to the nail that is wrapped with some copper wire. The end of the switch that isn't connected you connect to the electromagnet.
What would happen if you put both batteries in backward in a two cell flashlight?
Nothing would happen, the flashlight simply wouldn't work. Switch the batteries back around and it will work. This is purely because the contacts don't line up properly. A normal incandescent lamp will work either way round. A modern LED flashlight however is polarity sensitive.
What problems are there with reverse polarity?
Reversing polarity ,changes the rotation of the device you are changing polarity on.
What is the polarity of C Cl14?
Its polarity is zero.CCl4 is non polar
Is capacitor polarity sensitive?
Some capacitors are polarity sensitive; some are not. It depends on the design. Electrolytic capacitors, for instance, are polarity sensitive, while ceramic disc capacitors are not. You can generally tell, if the capacitor is marked with polarity signs, such as + and -, if it is or not.
Why the resistor does not have polarity?
they do not have any electrical property that is polarity sensitive
Are capacitors polarity sensitive?
The capacitors those are polarity sensitive are called electrolytic and tantalum capacitors. These capacitors are labeled as positive and negative.
How can you do the polarity test of a switch?
A 'polarity test', as it applies to a switch, is performed to confirm that the switch is located in the line conductor and not in the neutral conductor.
Why the diode called polarity switch explain?
A diode will only conduct electricity if the polarity of the current is in the correct direction, because diodes can only conduct in one direction.
What is a DIAC?
Diac is a bidirectional electronic switch that can pass current in either directions according to the polarity applied on it.
What happens if you don't connect the LED in its required polarity?
Why nothing at all, of course there will be no light.LEDs being diodes are polarity sensitive devices, which means they will only conduct electricity in one direction. Only when an LED conducts will it emit light.
Would reverse polarity cause equipment to run even if switch is off?
The case of reverse polarity would only happen on a DC system. As to would it cause equipment to run when switched off, no, if the switch opens the equipment's power supply completely the device will not operate.
Does it matter which way a emitter resistor is installed?
A resistor is not polarity sensitive, and may be installed in either direction. That's why resistors don't have pluses ( + ) or minuses ( - ) printed on them.
Any ideas why the dipped headlights on my corsa have stopped working - it is not the fuses.?
try changing the bulb or turning bulb around in the socket as the bulbs are polarity sensitive
What is a oil sending switch?
This is a pressure sensitive switch that controls the oil pressure indicator (light or gauge) on the dash board in the vehicle
What is a light sensitive switch?
this is due the action of the photo transducer.when the light falls on the swtich, suddenly the resistance decreases.and the switch is closed.
