Hi
Suppose we have a normal circuit, where an LED is powered by a source of 1V, we do not know the polarity of the source, and we want to raise the supply current of 1V to 20V without using switches and without removing the source of 1V .
What could be done?, This is a diagram I did, on the left there is the circuit without modification, and to the right, is a reference about how it should be.

Thanks
