Easy Battery Hack Using a DC Power Supply
For a given circuit, in my case, the toy, the resistance R is a constant. If I replace my batteries with a power supply of equal voltage, then the current in the system also stays the same. This project uses this relationship to replace Voltage, V supplied by a battery with voltage supplied by a DC power supply – nothing else is changed.
power supply
How can I make a device that will make the power connected as long as the voltage of the power-supply keeps over 12.4 V (adjustable) and disconnect it if it falls below? It also must connect the power back, but only if it rises above 13.5 V. This has to sustain at
