Floating output voltage in USB chargers?
A USB charger is usually galvanically isolated from mains for safety reasons.
If I touch the output connector while standing on the ground (i am at earth potential), will I get a shock? I think yes, ...

Earthing: TN in TT installation?
Something odd happened at work today: the whole building installation is TT, just like the whole country. L1-L2-L3 supplied to the transformer and then L1-L2-L3-N goes to the loads.
I noticed that we ...

I am driving a LT3092 current source with a variable voltage - to get a variable DC current, but the output needs to float 0 to 1.5V above ground
What type of buffer amplifier would work - either discrete opamps or a differential output opamp? The output voltage would ideally vary up to 12VDC. The variable current source has a variable load ...
