| problem.p.1 | "
Circuit schematic problems allow students to create virtual circuits by
arranging elements such as voltage sources, capacitors, resistors, and
MOSFETs on an interactive grid. The system evaluates a DC, AC, or
transient analysis of the circuit.

You can form a voltage divider that evenly divides the input
voltage with two identically valued resistors, with the sampled
voltage taken in between the two.

You can form a simple high-pass filter without any further
constraints by simply putting a resistor in series with a
capacitor. The actual values of the components do not really
matter in this problem.
