Ralph’s simple battery charger is essentially this simple voltage regulator circuit. He chose the voltage-setting resistors R1 and R2 to give him 2.5 V on the TL431 when the output sees 3.6 V ...

Adding more batteries to a simple circuit will increase the electrical ... A circuit always needs a power source, such as a battery, with wires connected to both the positive (+) and negative ...

Whee! So, Greg, that circuit that we made, would that work in real life?Yeah, absolutely. That was actually just a simple version of a circuityou might find in an electric car.A battery ...
