Reversed polarity in a 110-volt receptacle usually occurs when the hot and neutral wires are connected to the wrong terminals. This can happen due to incorrect wiring during installation, loose connections, or faulty outlets. It can be hazardous because it can lead to electrical shocks and damage to appliances or devices plugged into the outlet.

Can a 5 volt. 1500 ma. power adapter be used to run a 4.5 volt appliance?
No, get a matching transformer and check the polarity and the milliamps.
How can I install a 110 receptacle alongside a 220 receptacle using the 220 receptacle wires for power?
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
How many 120 V 20 amp receptacles are there?
To calculate the number of receptacles on a 20 amp circuit with a 120V supply, you need to consider the total circuit capacity. A 20 amp circuit can typically support around 10 receptacles. However, always consult local building codes and regulations to ensure compliance and safety.
Were would 240 volt plugs be in a house?
240 volt plugs are typically found near large appliances that require higher voltage, such as electric dryers, stoves, or air conditioners. They may also be located in dedicated utility rooms or in the garage for tools or equipment that require higher voltage.
Can a 20 amp circuit breaker operate two 15 amp receptacle?
It is perfectly acceptable to have (2) 120 volt 15 amp receptacles operated from a 120 volt 20 amp circuit breaker (as a general rule of thumb 11 receptacles are acceptable on a 20 amp circuit). The 15 amp rating of the receptacle is the maximum allowed amperage that should be hooked up to the receptacle at any one time. So in this case the limiting factor is the amount of current being drawn across both receptacles simultaneously should not exceed the 20 amp rating of the circuit breaker. In the United States the NEC code allows the use of a 20 amp circuit breaker to feed a branch circuit consisting of 15 amp receptacles. Generally you would not exceed 11 receptacles though as you will assume an average load of 1.5 amps per receptacle and trying to maintain about 80% max load.
Can you get -5Volts as output when polarity is reversed?
yes.you can get 5v output even when the polarity is reversed. In a 5v battery, if u reverse the polarity, then u'll get the same 5v as output , but in the opposite direction.(i.e.,)-5v(negative 5 volt
Is 24 volt DC is equal to -48 Volt DC?
No. The value and polarity are different.
What happens if the direction of current at the terminals of a series motor is reversed?
No changes will occur by wiring a 110 volt motor in reverse polarity, rotation will always be the same. Some single phase motors are designed to be reversed ,but that is a function of the relationship of start windings and capacitors and requires some wiring changes in a motor junction box or an end terminal housing, not by just changing the incoming power.
How do you test speaker wire polarity?
Observe polarity and touch a 1.5 volt battery to the terminals and note the direction the speaker cone moves.
Can a 5 volt. 1500 ma. power adapter be used to run a 4.5 volt appliance?
No, get a matching transformer and check the polarity and the milliamps.
How do you tell generator on 1983 Honda gl 1100 works or not?
Start the generator and check the voltage output at the receptacles on the generator with an AC volt meter.
How can I install a 110 receptacle alongside a 220 receptacle using the 220 receptacle wires for power?
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
What will happen if the supply voltage polarity is reveresed for the case of using a diode with piv of 4.8 volt?
If we give more than 4.8 volt to a diode in reverse bias condition it will break down or destroyed.

Can a 18.5 volt ac adapter 19 volt laptop?
Yes it is close enough. As long as the power supply ampere hour rating is as high or higher than the laptops requirements. Make sure the polarity of the plug is correct also.
When the hot and neutral are wired backward is reversed polarity?
The assumption here is that you're refering to a standard A/C (alternating current) circuit such as those found in the average household or business. In a typical household the power supplied by the power company actually reverses polarity 60 times a second (60 Hz), hence the term alternating current (A/C). In Europe the standard frequency or Hertz (Hz) is 50 at 220 volts. The U.S. standard is, of course, 110 VAC at 60 Hz. So, in answer to your question In most systems you have a 0 volt potential *neutral and a 110 or 220 volt potential *hot, when this gets wired in reverse safety problems can arise, such as a nasty shock when touching grounded equipment.
