RC circuit question? You need to construct an RC circuit with a time constant of 0.25 s, and you are given aselection of 1, 10, 100, and 1000 µF capacitors, and 1, 10, 100, and 1000 Ω resistors. Draw acircuit which accomplishes this task, labeling the resistance or capacitance of each component. Keep the circuit as simple as possible.
