A Low Pass Filter circuit consisting of a resistor of 4k7Ω in series with a capacitor of 47nF i,s connected across a 10v sinusoidal supply. Calculate the output voltage ( VOUT ) at a frequency of 100Hz and again at frequency of 10,000Hz or 10kHz.

I'm confused when they talk about the 10v sinusoidal supply.
20Vpp?
5Vpp?
Vrms?

Doesn't matter. If the input was rms, your calculated output will be rms. If the input is peak-to-peak, then your calculated output will be peak-to-peak.

I'm building the circuit on an app, and I cant seem to get the calculated value to match with the measure.
