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 a multimeter be connected in order to measure resistance?
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.
What will the multimeter show if it is used to measure the voltage of the ac half wave rectified voltage?
rms value of voltage
What type of measurement using a standard multimeter measuring AC voltage will the multimeter indicate?
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.
Methods of calculating Ripple voltage in supply without using oscilloscope?
Measure AC voltage with multimeter. It is easiest way to check how big ripple is. There is no way to 'calculate' value.
But in DC ciruit there is no current when capacitor is connected?
This is because when you introduce a capacitor, the circuit is no longer a DC circuit. If you're using a multimeter see if there is an AC setting to measure the current.
What are the three main function of the multimeter?
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
A multimeter can measure?
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
How do you use an analog multimeter to measure voltage?
Just set to AC or DC volts and probe the two points you wish to measure voltage across.
What instrument used to measure alternating current?
A multimeter has the ability to measure both AC and DC current along with voltage and resistance.

What is the peak voltage of a sine wave that measure 220V AC rms?
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.
A technician uses an oscilloscope to measure the peak value of an ac wave he tells you that the voltage has a peak value of 100v what is the rms value of the voltage?
100v divided by 1.41
On a standard three prong AC outlet what should the AC voltage measure between neutral and hot?
Nominally 120 Volts.
