1. The problem statement, all variables and given/known data A two-terminal “black box” is known to contain an inductor L, a capacitor C, and a resistor R. On connecting a 1.5 V battery, 1.5 mA flows. When an AC voltage of 1V RMS at 60 Hz is connected, 10 mA RMS flows. As the frequency increases at a fixed 1 V RMS, the current reaches a maximum of over 100 A at 1 kHz. Sketch the circuit in the black box and find values for L, C and R. 2. Relevant equations 3. The attempt at a solution I can't figure out how to start this one because of the phrase "on connecting the battery". I think that must mean immediately after connecting the battery, but I don't know how the circuit could be set up if that was the case because no current can flow through the capacitor when there is zero frequency. Can someone help me see how the circuit is supposed to be set up?
