I bought a Zhougong power supply, 48 to 12V; When the load is greater than 110 ohms, the 12V voltage is very unstable. When the load is less than 110 ohms, the output is normal. What is the principle?...
Manufacturers have IPC standards to follow for the sizes of components and PCB pads. I have read IPC7351, which clearly defines the formulas for calculating the sizes of components and pads, as shown ...
Make a white light LED lighting circuit (the kind of LEDs that are sold in the market now). I have never learned electronic circuits (general resistors, capacitors, symbols, haha...), so I want everyo...
Emergency hand-held lamps powered by 6V maintenance-free batteries are widely used in rural areas. The charger used is a transformer step-down and single diode half-wave rectifier, and the charging...[Details]
