If I have an electrometer, and connect a wire (acting as a sense antenna) to it, through a large value resistor, to turn it into a high impedance voltmeter, and I move a charged object close to the wire, and the meter reads negative current, does that mean the object is negatively charged, or is it positively charged, and it induced a negative voltage/current? -- --- Chris Smolinski Black Cat Systems http://www.blackcatsystems.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
