II. Introduction We apply an AC voltage with constant amplitude but Variable frequency Circuit variable frequency across a circuit element "X": element AC voltage source X We measure the voltage across "X" by wiring a Circuit real-time voltmeter across "X" and we measure the element current by inserting a real-time ammeter in series AC voltage source X with "X" A The "real-time" meters show the current or amplitude as a function of time. III. Predictions 1. For each element (resistor, capacitor, inductor, and series RLC circuit), sketch a graph of the current amplitude / vs. the frequency f (keeping the amplitude V of the voltage constant). Write a short explanation in each case.
