rms value of voltage
If the vswr (Voltage Standing Wave Ration) is high than call drop chance increase.
It is defined as the ratio of RMS value of output voltage to the average value of the out put voltage.
AC stands for "alternating current," which is a type of electrical current that periodically changes direction. It is not a wave but can be represented by a waveform, which shows how the voltage or current changes over time in a repetitive manner. So, AC is not a wave itself, but it produces a waveform when graphed.
due to the form factor .as the form factor of sine wave is 1.1 so, we use its multiples .
It is smoothing
It can take (almost) any form, but what comes out of your wall is close to a sine-wave.

define the maximum value of an ac wave form
The AC voltage is in the form of a sine wave. Half the wave is above zero volts and half below. In half wave rectification the bottom half of the wave is chopped off. That leaves a series of "humps' interspersed with a half wave time of zero voltage. The capacitor stores charge that decays through the resistor. The more capacitance the longer the charge is held and the voltage smooths out somewhat to approximate a DC voltage with some ripple. A full wave rectifier flips the bottom half of the waveform above zero so that the period of time the voltage is close to zero is reduced and the less ripple in the output voltage and the capacitor will smooth out the voltage even more.
if that 144 is the peak voltage if its a sine wave the rms voltage is that voltage divided by sqrt(2) if not a sine wave (modified) you must find the area under the curve by integrating a cycle of that wave shape (root mean squared)
First rectify the voltage signal then pass it through galvanometer. its reading will give the rms value, so multipy it with form factor to get amplitude of the signal. Form factor for sinusoidal half wave and full wave are 1.11 and 2.22 respectively. One should also take care of voltage drop accross the rectifier diodes in calculation.
The effect of an RL circuit in half wave rectifier is that the voltage output wave forms for current and voltage will be modified .
A half wave rectifier does not make a stable voltage. A single phase half wave creates a "bumpy road" where voltage modulates between sine wave maximum and zero. A three phase half wave will create a more stable, but ultimately "unclean", voltage.
