Because inductor accept low frequency so voltage should be measured across resistance. |

Since a filter is only placed to remove ripples, if we place filter in the middle of the circuit it causes voltage drop which leads to reduction in the actual magnitude. So, we have to take the output across resistor by placing the inductor in the middle of the circuit. |

Let input be V<0, since are and L will be in series so current will lag the voltage by some angle. As the output is taken across the inductor, the voltage drop across the inductor will be the product of impedance of inductor and current which means the output will lag the input. So, the answer should be true. |
