How do you identify positive terminals in voltmeters and ammeters?
The positive terminals in voltmeters and ammeters are generally indicated by a red coloring and a + (plus) symbol. Negative is generally black and - (minus).
Why is an AC voltmeter a second order instrument?
DC voltmeters take the average of a set of samples. AC voltmeters work out the RMS voltage (root-mean-square) of the signal which is defined as: VRMS = The square-root of the intergral over one period of v2(t)
When was the Volt Meter invented?
Voltmeters were made possible by an 1819 discovery by Hans Oersted. The first voltmeter were made soon after that.
An ammeter is used for what?
An ammeter is an instrument which is used for measurement of current flowing in any circuit
How many types of Digital voltmeter?
There are two main types of digital voltmeters: integrating digital voltmeters and integrating analog-to-digital converter voltmeters. Integrating digital voltmeters are based on the principle of integrating the input voltage to measure it accurately, while integrating ADC voltmeters use an analog-to-digital converter to convert the input voltage to a digital reading.

Is a voltage scale analog or digital?
analog Voltmeters come in both forms depending which one you buy.
What do voltmeters test?
Voltmeters provide a direct, difference of potential measurement or test.
How are voltmeters connected in a circuit: in series or parallel?
Voltmeters are connected in parallel in a circuit.
How can you tell wheter two charges have the same magnitude?

What are the advantages when using a digital voltmeter?
The electronic voltmeter has higher input impedance than other voltmeters, such as traditional VOM's. As a result, it loads the circuit under test to a smaller extent, introducing a smaller error in measurement. Many electronic (or digital) voltmeters have an 11 Megohm or 20 Megohm input impedance, as opposed to a typical 20 Kiloohm per volt impedance of a typical VOM with a 50 microampere movement. Some high end electronic voltmeters have an input impedance well into the thousands or millions of Megohms.

How much better are slr digital cameras than the conventional digital camera?
SLR digital cameras are professional grade cameras which have settings which may be manipulated to produce outstanding photos that otherwise could not be achieved with a regular digital camera
