12/24/2023 0 Comments Electrical polarity![]() ![]() In the above circuit, whenever the battery is connected properly it makes the MOSFET switch ON by allowing the flow of current throughout it. If the voltage supply is above the Vgs then you have to drop the voltage in between the gate & source terminals. So you have to connect just the MOSFET’s gate terminal to the GND. If the voltage supply is below the Vgs (gate-to-source voltage) of the MOSFET then you need only the MOSFET without a resistor or diode. If the electrical wires are not connected correctly, then it is known as reversed polarity so it can cause electrical shock when anyone touches the outlet or device & even harm to the device itself. Generally, positive wires are normally in red (or) black color that must be connected to the brass terminal whereas Neutral wires are normally in gray or white color, they must be connected to the chrome terminal. Before checking the electrical wiring, you must turn off your electricity supply. If you notice that outlets of your home wall have this polarity, then correcting the trouble is difficult, but, you have to be cautious otherwise you can get shocked (or) electrocuted. For instance, reversing a motor’s polarity could cause it to revolve in the reverse direction, whereas reversing a magnet’s polarity could cause it to keep away instead of attracting other magnets. This polarity has many effects based on the involved equipment or device. Reverse polarity in a circuit can affect or damage the electrical circuit or devices, thus it is very significant to understand the effects before trying to do so. Reverse Polarity Is Reverse Polarity Dangerous? The reverse polarity in the AC circuit changes the AC wave direction. The reverse polarity in a DC circuit means, changing the positive & negative connections so that the flow of current will be in the reverse direction. But, whenever this polarity happens, then it leads to hazards and potential issues. ![]() Generally in the standard configuration of polarity, the positive terminal (+) is connected directly to the positive side whereas the negative terminal is connected to the negative side of a power source. Reverse polarity can be defined as an electrical condition where both the terminals of a DC system are connected mistakenly in reverse. This article provides a brief information on reverse polarity. Whenever the current flows between two poles or points, if one of the poles has more electrons than the other pole, it is negative polarity whereas the pole with fewer electrons is known as positive polarity. Whenever the two poles are simply connected through a wire then electrons will flow from the negative to the positive pole which is known as electric current. Similarly, reverse polarity is quite opposite to it which means it is a condition where an outlet’s electrical wires are connected simply in reverse. The term ‘polarity’ is used in different fields like electricity, electronic signaling, chemistry, and magnetism to explain the flow of electrons. The term ‘Polarity’ can be defined as when an entity has two different & reverse poles that can either repel or attract each other. ![]()
