Obviously, it's a voltmeter that measures a.c. voltages. The most common types are a 'moving iron' type or a 'moving coil' type. The latter requires a rectifier circuit. Both scales are calibrated to indicate root-mean-square values. Moving-iron scales are non-linear, whereas moving-coil scales are linear. Moving-iron types are less accurate than moving-coil types.

How is an ammeter converted to a voltmeter?
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter. If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.
Why shouldn't ammeter be connected in parallel?
A: An ammeter actually is a voltmeter measuring the voltage drop across a very small shunt resistance. They can measure AC or DC, make sure the meter is rated for the anticipated current, and always connect in series.
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
When measuring with an ammeter the ammeter must be connected in?
When measuring a load current, an ammeter is connected in series with the load. The exception is for a clamp on style AC ammeter, which is clamped around one of the conductors, making its measurements as a transformer.
Which instrument is suitable for measuring both a.c. and d.c. quantities.?
We use the "MOTOR GENERATOR SET" to convert the DC power to AC power we use DC motor and ac generator in it. It is very efficient way to convert the DC power to AC power.
Can a multimeter be used as substitute of ammeter and voltmeter why?
yes it can read both ac and dc voltage and current .AnswerThe whole point of a multimeter is that it can perform the function of an ammeter, a voltmeter, and an ohmmeter!

What is the difference between ac ammeter and dc ammeter?
dc ammeter has three connecting pins while ac has four
Why DC ammeter or voltmeter is not used in AC circuits?
Short answer, because it is designed for DC, not AC.In AC, the current goes back and forth all the time; the average current is zero. And that's what a galvanometer that is not especially designed for AC would show.
What is used to monitor line voltage sag?
An AC voltmeter is ideal. If you really want to get fancy and analytic about it, you could use data-acquisition equipment to constantly read the AC voltmeter, and store or record the data.
What is an ac voltmeter?
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
When an AC 5A and dc Current of 5A applied simultaneously to the circuit then what it happen?
A DC ammeter will read zero
What kind of ac ammeter does most electricians use?
I use a Fluke ammeter.
Concept of ac voltmeter?
Red wire from a regular DC voltmeter should be connected to :
How do you wire in a voltmeter?
A voltmeter needs to be connected in parallel with the part of the circuit you are checking. It records a change in voltage, and has a high internal resistance, so it cannot be connected in series unless you want to screw up the circuit. Set the meter to AC or DC volts and place the wires of the terminal across the resistor, switch, or any other potentially resistive part of the circuit.
What instrument measures electrical signals?
The following instruments can all be involved in a measurement of electrical signals, depending on whether the signal is in wire or in the air, and depending on which of its properties and characteristics you want to measure: -- AC voltmeter -- AC ammeter -- power meter -- frequency counter -- field strength meter -- BER counter
Why shouldn't ammeter be connected in parallel?
