How do you explain negative voltage?
A negative voltage is a relative excess of electrons compared to some other point. If 0 V is no voltage. Negative voltage is an excess of electrons and positive voltage is a deficiency of electrons.
Is negative voltage possible?
The magnitude of a voltage can be either positive or negative. If the voltage magnitude is positive, the voltage has the same polarity as shown on the diagram. If the voltage magnitude is negative, the voltage polarity is the opposite to that shown on the diagram. Voltage is measured using a voltmeter.
What happens when there is a voltage spike?
This can lead to breaks and cracks in the wires or even explosions. Either way, surges and spikes may lead to equipment failure. Voltage spikes and surges can be caused by lightning, static electricity, magnetic fields, and internal changes in voltage use.
What does it mean when a voltage source is negative?
A voltage source has positive or negative polarity depending on its orientation in a circuit. In the case when a voltage source has negative voltage, it just means the negative terminal of the battery is connected to the positive side of the circuit and the positive terminal of the battery is connected to the negative side of the circuit.
What causes a spike in the Motherboard voltage?
This can cause a spike or surge in the rest of the system. For example, when the fan that cools down your computer turns off, it can create a spike or surge in the motherboard of your computer. A large enough spike or surge will damage your equipment. The best way to protect your circuits is with the use of a surge protector or surge suppressor.
Can a transistor be switched to negative polarity?
Yes, if you switch the orientation of a voltage source to negative polarity for many circuits, the circuit may not work anymore, but in other circuits, negative voltage has extreme use and cannot work. One example of an electronic device that many times uses negative voltage is a transistor.
