eli5: ground vs negative terminal. are they the same thing?
Not necessarily but, by convention, generally yes. Ground is nothing more than a baseline reference for all the voltages on a circuit. You start with whatever voltage your power source provides and call negative to the 0V pole and positive to +24V (or whatever) pole. Ground is always 0V so ground, negative and 0V all mean the same.

What Happens If You Connect Positive to Negative on a Car Battery
When connecting a car battery, it''s essential to connect the positive terminal to the positive cable and the negative terminal to the negative cable. Connecting the terminals in reverse order can cause a great surge of electric current between them, leading to a lot of hydrogen being produced from a series of chemical reactions.
How Do Batteries Work? | OpenLearn
To kickstart the chemical reactions in the battery, you just connect a wire between its negative and positive terminals, and a steady stream of electrons (a current) is produced as the reactions get under way. If an …
7. Ground, earth and electrical safety
Earth is a direct physical connection to the Earth. This is usually done by driving a copper rod (earth stake) into the ground. But, depending on age and location of the system this can also be a copper plate or copper strip buried in the ground, or the water mains or
What Happens When You Connect Wires to a Battery?
Connect Positive And Negative Terminals Together It is a common misconception that connecting the positive and negative terminals of a battery will result in an explosion. In actuality, doing this will simply cause a …
Electronics Schematics: Ground and Power Connections
Thus, voltages are always relative. For example, the positive pole of a AAA battery is +1.5 V relative to the negative pole. At the same time, the negative pole of the battery is –1.5 V relative to the positive pole. Now …
Understanding Battery Polarities: A Diagram
When connecting batteries in series, the positive terminal of one battery is connected to the negative terminal of the next battery, creating a cumulative voltage. In parallel …
The Ultimate Guide to Powering Your Arduino Uno Board
You can supply power to the Arduino Uno using an AC-to-DC adapter connected via the board''s power jack. This jack is typically fitted with a 2.1mm center-positive plug. Another alternative is using a battery, and in cases such as this, it is best to connect a 9V battery directly to the power pins (Vin and GND).
