Multiple ChoiceIn introductory electricity, what SI unit is used to measure the strength of an electric current?
Multiple ChoiceTopic: Intro to Current. Two cylindrical copper wires have the same length but different diameters. Wire A has diameter dA and Wire B has diameter dB, with dB>dA. If the same potential difference V is applied across each wire, which wire can carry the higher current?
Multiple ChoiceTopic: Intro to Current. For copper wire of the same length, which American Wire Gauge (AWG) will carry the most current before excessive heating (i.e., has the lowest resistance)?
Multiple ChoiceIn introductory circuit analysis, which wire gauge (American Wire Gauge, AWG) will typically carry the most current safely (all else equal, such as material and length)?
Multiple ChoiceIn introductory circuit analysis, which American Wire Gauge (AWG) wire can typically carry the most current (assuming the same material and similar insulation/ambient conditions)?
Multiple ChoiceIn an introductory circuits context, which device restricts electric current flow to a single direction?
