Quizplus · Accepted Answer

The cutoff frequency ($f_c$) of a circuit, especially in the context of RC (resistor-capacitor) circuits, can be calculated using the formula $f_c = \frac{1}{2\pi RC}$, where $R$ is the resistance in ohms and $C$ is the capacitance in farads. Without the specific values of $R$ and $C$ provided in the question, the exact calculation cannot be shown. However, given the options, 72 Hz is a reasonable estimate for a typical RC circuit's cutoff frequency, as 3 Hz would be unusually low, and 455 Hz and 723 Hz would generally require significantly smaller values of $R$ and $C$, or a different type of circuit configuration.
