6 FAQs about [Negative value of battery voltage]
What happens if a battery has a negative orientation?
If a battery has negative orientation, its voltage with respect to ground is more negative than ground, and it delivers positive current to the ground part of a circuit. To find out how to obtain negative voltage from a DC power supply or a battery, see . Negative voltage is not always unintended.
What does it mean if a voltage source has negative voltage?
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 . Look at the diagram below for an illustration of positive and negative voltage:
Is a negative voltage equal to a positive voltage?
Positive and negative voltages are approximately equal in value but opposite. Opposite in the sense that negative voltage is an excess of electrons and a positive voltage is a deficiency of electrons. A battery is a very quick negative voltage source. What does a negative current mean?
Does a battery have a negative electrode?
A battery does not have a negative charge, but rather a negative electrode. The positive terminal becomes the negative end and will meter -V when tested normally. This is a rare occurrence, but it happens when a single cell depletes before the others and is deep cycled to 0.00v.
