AI Customer ServiceI am at a loss how negative voltages are a mystery. Ordinary AC has negative voltages. Connect the positive of a battery or isolated power supply to the common, and you have a negative voltage w r t common. The 7805
AI Customer ServiceTo use a battery to create a negative supply: Obtain a 9V transistor battery or a 4 or more cell AA alkaline battery pack or other source of 5V or more. (Or a mains "plugpack" power supply of 5V or more.) the -ve terminal will be at -V. eg a 9V battery will give -9V etc. +1 for "use a better op amp".
We’ve seen that batteries are often depicted as a circle with a positive (+) and negative (-) symbol indicating the positive and negative terminals: This symbol indicates a generic DC power supply.
Because batteries have a positive and negative terminal, they are ideal for use in dual balanced power supplies. Dual-voltage power supplies typically have a positive and negative power source that is equal in voltage value but opposite in polarity, in addition to a zero ground point midway between the two voltages.
Sometimes you may also hear the two terminals referred to as negative and positive electrodes, but this is not technically correct; the electrode is the conductor inside the battery that connects the terminals to the electrolytic fluid in the electrochemical cell. Here’s what a DC source (1.5 V battery) would look like in an electrical schematic:
The difference in charge causes electrons to move through the wire towards the positive terminal of the battery, where they are removed from the wire. At the same time, the negative terminal supplies more electrons to the wire, so the charges don’t continually build up at the battery terminals.
Anything that uses a battery is relying on a DC power source. Cell phones, laptops, cars, and cordless appliances like drills or even wine-bottle openers all use batteries as a source of direct current. If a device uses a battery as its’ power source, internally it is comprised of DC circuits.
