So popped on something that came to mind ... $\displaystyle V = IR$ $\displaystyle I(T) = \int_{0}^{T}{\frac{1}{L} V(t) dt}$ Has anybody messed with any cool current meters - that work with 120V lines, are accurate and not too expensive - and not too fragile. BTW - when you look at a post, can you get to the original Tex to see how people entered it? I haven't been able to figure out how yet.

If you quote the message with the code in it you can see how it's done.
