You'll have to excuse my sheer lack of knowledge, I'm sure this must be among the most basic of questions posted on here.
I have a dynamo (motor), which is powering an LED (for argument sake).
If the dynamo stops spinning, the LED's no longer powered.
Is it possible to power the LED with batteries that are currently being charged? So, if the dynamo stops the LED has a bit of power left in the batteries to carry on using until the dynamo starts spinning again?
Worth noting, these are all very small, low-powered devices I'm talking about. Nothing of scale.
Thanks very much
