Answer the following statement(s) true (T) or false (F)
1. Voltage is always measured between three points of different potential. 2. We use an instrument known as a voltmeter to measure voltage. 3. Electron theory defines current flow as a motion of free electrons from the negative pole of a source, through the outer circuit path, and back to the positive pole. 4. In measuring the rate of electron flow, we are concerned with simple speed rather than a quantity rate. 5. Common materials of highest resistance (so high it is difficult even to measure) are the least effective insulators.
