情境
A hand crank dynamo generates low-voltage AC, which is rectified by a bridge and stored in a capacitor; a manual switch connects the energy to an LED through a current-limiting resistor.
這張圖裡有什麼
看懂背後的決策。
01
Use a bridge rectifier to convert the dynamo's AC output to DC
02
Add a bulk capacitor to smooth and store the rectified energy
03
Insert a series resistor to limit LED current and a switch for manual control
Use for portable, manually charged LED lights or any low-power hand-crank generator supply needing rectification and current limiting.
