התרחיש

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.

מה מופיע בתרשים הזה

פענחו את ההחלטות שמאחוריו.

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.
