"Can resistive attenuators be used for AC as well as DC?"
Of course they can.

:)

A student asked if resistive attenuators can be used for AC as well as DC. This is a simple demonstration showing resistors used to attenuate both a DC and a 1kHz signal by a factor of 2 (a gain of 0.5). Some of the pros and cons of resistor attenuators are briefly introduced. The resistors are assumed to be ideal so the high frequency effects of their parasitic capacitances are not shown. However it is easy enough to add them if anyone wants to play with the simulation.

Updated to show how to attenuate a current by providing two (or more) paths for it to be split down.
