Emergency Power Based On Cordless Drill Batteries
Exactly. This is getting annoying. We get it already, grab a battery and an LM7805 or LM7812 and you can have 5v USB or 12v "Car" power. This is practically identical to the lame ass one HaD ...
batteries
But the ground pin is always connected to the "negative" power supply or the negative part of the battery. This would be like connecting the negative end of the same battery to the GND pin. As you can see with an isolated power supply you can connect ground to
Should my 24vdc power supplies be floating or negative earth ground? : r/PLC
Inside the battery charger at the full wave bridge rectifier, a center point ground is created between the + terminal, a ground detection resistor (~10k-20k) ohm as well as the negative terminal. Those resistors both give the charger to measure & detect voltage imbalance as well as give everything connected a ground reference.
Difference between negative terminal and copper ground?
If the power supply is a battery, and the devices in the circuit are designed for a positive supply, then the negative terminal serves as the ground. The positive terminal could also be ground, if all the circuits are designed for a negative supply.
