What else can I help you with?
What problems are there with reverse polarity?
Reversing polarity ,changes the rotation of the device you are changing polarity on.
Can speaker reverse polarity damage speakers?
No. Reversing the polarity does not damage the speaker. The only issue in connecting it backwards in a stereo setup is the speaker cones will not be moving in sync with each other, so stereo imaging and bass response will suffer.
How magnetic trains stop?
By reversing the polarity of the magnets and there are also friction brakes.
Will reverse polarity damage equipment?
Reversing polarity will most likely damage electronic equipment, especially semiconductor components such as transistors, diodes and LED devices if the voltage is high enough. Other devices may not function at all, will be unaffected (such as incandescent light bulbs), or may work backwards (such as some DC motors.
The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
How do you reverse polarity on ac motor?
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.
Is there any necessary to mark polarity on capacitor?
For electrolytic capacitors, yes, as ignoring their polarity can damage them.
What are the top causes of exploding car batteries?
Hooking the battery cables up incorrectly. Reversing the polarity can cause the battery to explode.
What is the impact of reversing the polarity of a CT in a 3phase and 4wire metering arrengement?
The net measured power would appear to be negative, or reversed.
What are the effects of reverse polarization in electronics?
When a magnet's polarity is reversed, the changing magnetic lines of force cutting across wiring induces a voltage in them. This principle is used primarily in motors. Or perhaps this refers to applying DC power to a device in reverse polarity by mistake. If the device is well designed, it will have a safety diode in the power input area to prevent damage, but if the diode is not present, reversing the power polarity will probably destroy every semiconductor junction in it.
A diode does what?
A diode is a semiconductor meaning it will conduct from anode to cathode if the anode is held positive. Reversing the polarity Will in effect block current flow.
