This simulation shows the impedance triangle for a series RLC circuit. The impedance (Z) of the circuit is the
hypotenuse of the triangle. The resistance is the horizontal side of the triangle. The vertical side is the sum of the
inductive reactance (XL, in the positive y direction) and the capacitive reactance (XC, in the negative y direction) vectors.

The maximum current is the maximum voltage divided by the impedance.

Given the limits on the sliders, see if you can determine the maximum and minimum values of the impedance and the current.
