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.
To measure ripple AC voltage, use an oscilloscope or a true RMS multimeter. Connect the oscilloscope probes across the output where the ripple voltage is present, ensuring proper grounding. Set the oscilloscope to an appropriate time base to visualize the waveform, and measure the peak-to-peak voltage to determine the ripple magnitude. For a multimeter, select the AC voltage setting and connect the leads across the same output to get a reading of the ripple voltage.
A: A multimeter is an instrument design to measure ohms volts and amps. So to measure amps a shunt is provided to allow a sample of the current to be measured as a function of voltage.
rms value of voltage
Multimeters measure AC in two primary ways... The older style meter uses a diode, capacitor, and resistor to measure the peak voltage of the AC signal. They then compensate their calibration to read in a close approximation of what the RMS value will be. Problem is that this only works well for true sinusoidal waveforms - if the waveform is triangular, for instance, the indicated value will not match the RMS value. The newer style meter, if it states that it is a true RMS meter, will sample the input waveform and actually calculate the RMS value. This is done by adding up the squares of the input, and then taking the square root of the result. That is a much better approximation of how much power the waveform can deliver.
When testing AC voltage, you would place the probes of a multimeter across the component or circuit where you want to measure the voltage. Ensure the multimeter is set to the appropriate AC voltage setting. For safety, make sure to use insulated probes and avoid contact with live wires. Always follow proper safety procedures when working with electrical circuits.

To measure AC voltage using a multimeter, set the dial to the AC voltage setting. Connect the black probe to the common terminal and the red probe to the voltage terminal. Place the probes across the circuit or component you want to measure. Read the voltage displayed on the multimeter screen.
you can measure ac using a cathode ray oscilloscope. it will project a sinusodial waveform, showing that the current is in the positive direction in the first half and the opposite direction in the second half
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
A multimeter is used for measuring electricity and because it has many different functions, it has been named a "multi"meter. They generally measure AC and DC voltage, amps, and resistance (ohms).

rms value of voltage
Just set to AC or DC volts and probe the two points you wish to measure voltage across.
A multimeter has the ability to measure both AC and DC current along with voltage and resistance.

Peak voltage will be 1.414 times the RMS. Peak to Peak voltage, assuming no DC offset, will be 2 x 1.414 x the RMS value.
To check an outlet using a multimeter, set the multimeter to measure AC voltage. Insert the black probe into the common (COM) port and the red probe into the voltage (V) port. Then, touch the probes to the outlet's live and neutral terminals. If the multimeter reads around 120 volts, the outlet is working correctly.
