batteries
Basically what they mean is that if you have two good batteries in series with a bad battery, and you load the battery stack with a very large load, The ESR of the bad battery
ELI5: Since electrons flow from negative to positive, why are cars
The direction electrons flow is, in terms of circuitry, irrelevant. Voltage is actually relative, and does not exist without two terminals. For instance, if you have the negative terminal grounded
Chemical cells
The electrode attached to the negative terminal of a battery is called a negative electrode, or cathode. Swapping the two electrodes means that the recorded voltage becomes negative.

"A negative voltage is really a positive earth potential. If your positive conductor i(+) is earth, you can''t short it to earth. It can be shorted to the exchange earth connection if it
Why do we place a negative cable to the ground instead of the negative
"A more direct return path allows for better current flow and less voltage drop, like plugging a big appliance directly into an outlet, rather than via an extension cord." This question is asking
Lithium Battery Chemistry: How is the voltage and capacity of a
First of all, it should be clarified why a voltage between the positive and negative pole can be measured. The voltage window of lithium-based batteries is defined by the partial

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:
Do you get negative voltage in a circuit?
But sometimes you get negative voltage in a circuit, and it’s good to know what it is. One example where you get negative voltage is in the astable multivibrator circuit. Sometimes you see circuits that need a power supply with three connections, for example, +9V, 0V, and -9V. This is very common for amplifier circuits.
What is the difference between positive and negative voltage?
Fundamentally speaking, positive and negative voltages are not as different from one another as you might think. Both positive and negative voltages represent potential energy relative to a reference point (e.g. ground) at which the electrical potential is considered to be zero.
Why does a positive battery have more protons than a negative?
If electrons make one side of the battery negative, then the other side is lacking those electrons and wants them. Because the positive terminal is lacking those electrons it has a much more positive voltage. It likely has a lot more protons (which are positive) than the negative side of the battery.
Is negative voltage always unintended?
Negative voltage is not always unintended. 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.
