Is it safe to connect the battery to the power source
But on one battery USB output, the voltage dips down to 3V as different parts turn on/off, that''s too low for the esp32 and it becomes unstable. Adding 4x100uF caps across the power rail didn''t help. When they are on separate battery USB outputs, the battery maintains a steady 4.8-5V. I guess there''s not much I can do about it, they have to be ...

Is it safe to measure AAA battery current with a multimeter directly ...
But is a bad way to test a power source. When testing a power source we use a "load". Generally a resistor which has the capacity to dissipate the power we are about to put into it from the power source. We chose the resistance of the load to be the equivalent of what we normally use the power source for. For example, a 1.5 volt incandescent ...
if a laptop is plugged into a power source is it running with ac power ...
When you have a power supply, it needs to provide the correct voltage. If there is enough current it will run the computer. If there is more current available then the computer requires to run it will charge the battery with the excess, and if it''s not enough, the battery will provide power to top up the difference.
power supply
This page has a good answer: "it depends". The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.
Connecting arduino and separate power supply grounds
I am working on an arduino project that uses transistor switches to power on high power leds that are powered by a separate 24 volt power supply.
