Gordianus's latest activity

I keep almost all of them. I had to work many hours to buy those books and I'm attached to them. Math and Physics books don't get outdated.

We're dealing with an open surface and we should choose the normal vector (I know I'm a bit pedantic).

I have another concern- The current sources can't perform whenever any of the switches is open. The circuit makes no sense.

Could you draw the voltmeters?
