Learn MoreMost batteries, the power sources we rely on for countless devices and applications, output direct current (DC). This means that the electrical current flows in one constant direction, unlike alternating current (AC), which reverses its direction periodically.
Learn MoreFor the windows laptop event log power source change, how can I tell if it is switching from AC power to battery or from battery to AC power? I attach a screenshot here. It seems impossible to tell from the Windows Event Log. Internet search does not provide any answers.
Learn More3 · Direct Current (DC): Definition, Symbol, and Examples
Learn MoreThe DC power on the left-hand side shows the top voltage is higher than the bottom voltage by V1 which is +20V. The middle element must have the same voltage drop, so V2 is +20V. ... The DC current is a power source because the current enters into the negative terminal and leaves from the positive terminal. Example 2:
Learn MoreMost laptops will show a percentage charge for the battery while on mains power, and this requires that the battery be isolated from the main internal power supply DC-DC converters. Figuring out the state of charge for the battery involves a complex voltage monitoring or power state IC embedded in the battery pack.

Learn MoreThe 5V power supply was too large. When I hooked up a 3V power supply, the LED string functioned properly with the correct amount of light output/brightness. I realized that I didn''t have to worry about the current rating of the power supply, so long as it was enough. The current is pulled as needed by the LED lights up to as much as it needs.

Learn MoreIf your device runs on a battery, it''s DC, as all batteries use direct current to function. You might assume that something uses alternating current because you can …
Learn MoreFor any circuit to operate correctly, there must be a closed loop for current to flow. Therefore, current does flow through the return path (system ground, in your circuit).. Consider: simulate this circuit – Schematic created using CircuitLab. As you can see, current flows around the entire circuit (dissipating most of its energy across the load) and …
