Neither. A.C. voltage, and current, are expressed as root-mean-square (rms) values, and this is what a voltmeter and an ammeter reading will indicate. To measure peak voltage, or peak-to-peak voltage, you will need to use an oscilloscope.

how which is right and which is wrong. You need a voltage standard with that you can calibrate both to the standard
What it means is that those rated values may not be exceeded, they are the maximum that the machine can take.
The ratio of RB1 to RBBO is the intrinsic standoff ratio. It is the standoff voltage ratio to the power supply voltage.
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
It depends upon which country you live in. There are two standard voltage ranges used 1) 220 to 240 volts and 2) 100 to 127 volts. In both cases the voltage is alternating and the values stated above represent the "root mean square" (RMS) voltage. The actual peak voltage will be greater than the RMS values by a factor of the square root of 2 (approx 1.4 times greater).

The standard voltage is the Republic of Ireland is 220 VAC at 50Hz.

Relationship between values goals and standard
A potentiometer is a variable resistor, while a voltmeter is a device that measures voltage.
volt
the voltage of a laptop charger is in between fifteen to twenty four voltage.
carbon resistors of standard values are manufactured because other values can be obtained by series and parallel combination of standard values. Moreover even standard values do not offer exact Resistance's will have tolerance
'Nominal' means 'named'. So a 'nominal' voltage is the named voltage of a system. For example, when we talk about a 120-V or 240-V system, we are describing their nominal values, not their actual values which can change from moment to moment.
