Why would you need a low-pass filter for a curret control lab? (Embedded System)

Solution

When we use the Frequency filter of 1khz ,we must have the circuit values ranges of 1 volt of voltage and 100mH of inductor if present and thus we obviously get higher current range of 100mA

Thus we have to increase the frequency upto 10MHz and it is acquired by using the Active low-pass filter then we get the voltage ranges of 10mV to 100mV thus accordingly we get the low range of current values of range varies from 1mA to 10 mA.

Thus by using active low pass filter in the current controlled lab we get these low ranges of current to control easily
