An updated version of the AP Physics C reading chapter on current electricity. Section 24.14 has been polished to provide a high-contrast, professional explanation of ammeters and voltmeters, detailing their proper connection types (series vs. parallel) and the physical necessity of their ideal internal resistance levels to minimize loading effects. A cleaned-up Figure 24.6 provides a clear schematic reference. Content on the Wheatstone Bridge has been removed.
