For this part of the problem a voltmeter (with an internal resistance less than infinity) is connected to the system, where the contact points are on the upper and lower surfaces and are in the same vertical plane. choose the correct answer for the case where the sign of the charge of current carriers are either negative (electrons) or positive (holes). 1. the direction of the current through the voltmeter is upward for either positive or negative charge carriers. 2. the direction of the current through the voltmeter is downward for positive charge carriers and upward for negative charge carriers. 3. the direction of the current through the voltmeter is upward for positive charge carriers and downward for negative charge carriers.
