Why does your digital multimeter read ac and dc on same terminal?

The switching of the circuitry is done internally for the different voltages. This is done when you move the switch on the front of the meter from AC to DC.

What are the Conclusion of analog and digital multimeter?
The only different is one has a needle, the other digital numbers-same as with analog and digital watches.
How many ohms will a multimeter read for an open circuit on a car?
As close to zero ohms as makes no difference.Zero, or close to it. It should be nearly the same as if you touch the probes together.
Why does every ammeter in a circuit have the same reading?
If you're connecting it properly, then I would have to guess that the multimeter is defective.
What is uses of digital multimeter?
A digital multimeter is a instrument which is used to measure voltage, current, resistance also it can measures frequency and periodic waveforms. It manly used as test equipement, for example if you had created a circuit you can use it to see if there a fault so then it can be corrected. Digital meters tend to be more accurate, as they have a very high input impedance, so have less affect on the circuit being measured. Having a digital output gets round the parallax problem reading a needle. Having no moving parts, makes them more rugged and less likely to get out of calibration. The only downside of a digital meter is its harder to see a fluctuating measurement. Watching a needle is better in this case, than watch numbers change.
What is the function of the multimeter?
The same as the function of analog multimeter, but with greater precision and accuracy.measure voltage (both DC and AC)measure current (both DC and AC)measure resistanceSome digital multimeters can also do other things:measure capacitancemeasure inductancemeasure frequencymeasure temperature remotely (usually using a thermocouple probe)measure current without breaking the circuit (using a clip on magnetic probe)test semiconductor devices (diodes, junction transistors, field effect transistors, etc.)AF and/or RF signal generatoretc.

What is better a digital multimeter or a volt ohm meter?
'Multimeter' and a 'VOM meter' are different terms for exactly the same thing -a meter that can be used to measure voltage, current, and resistance. These meters can be either analogue or digital. Analogue instruments are now being priced out of the market by digital meters, due to the manufacturing costs of analogue instruments. Digital meters are more rugged and easier to read than analogue instruments, but not necessarily more accurate.
Why does a multimeter display a reading of zero when both of its probes are touched to the same end of a battery?
A multimeter? Zero because there is no voltage difference, zero because there's no current flow (amperage) and zero ohms of resistance because they are both touching the same metal terminal. Or, perhaps it reads zero because you have it turned off.
How do you read hyper terminal data to a file?
I have the same problem............ I want to read and write file but using Xmodem..... Please help me out as soon as possible
Is the Axon terminal the same as the terminal buttons?
yes

What two times on a digital clock read the same forward as they do backwards and are 2 minutes apart?
9:59, 10:01
Count in multimeter?
The "count" of a multimeter refers to how large a number it can display before it has to change measurement ranges, and how many digits it shows total. This affects how precise a measurement the meter can display (note: this doesn't necessarily reflect absolute accuracy, just precision of the numbers it can report.) First, the total number of digits of the count matches the digit count of the display. A x00 count multimeter only displays 3 digits, while a x000 shows 4 digits. So a 200 count meter could read 19.9 volts, while a 2000 could read 19.91 for the same input. Second, the value of the first digit indicates when the meter needs to "move up" to the next range. A 2000 count multimeter would read 19.99 volts as 19.99, but at 20 would have to read 020.0, loosing a digit of precision. The same thing happens at higher and lower ranges, each time having to move when the top digit reaches 2. For comparison, a 4000 count multimeter would up-range whenever the top digit gets to 4, allowing it to read 20-39.99 volts with two decimal places where the 2000 cannot. I suspect, but cannot confirm, the count limits in digital meters are due to the A/D converter used, and the number of output bits it has. This matches up with the common count values being close to powers of two.
What are analog instruments?
Analog instruments take an level of signal and convert it to a read out. As opposed to digital instruments whereby the same signal is processed digitally to display the same results
How do you check a diode?
the diode will have two polarities anode and cathode .take multimeter and set it in buzer mode or resistance mode and connect the positive terminal of multimeter to anode of diode and negative to the cathode the multimeter shows the resistance say 500-700ohms if it working and doesn't show any impedance i.e, very high impedance in reverse bias i.e, by connecting the positive terminal of multimeter to cathode of diode and negative terminal to anode,and in no working condition it shows same characteristics as in reverse bias connected. the simple way of checking diode is connect the 2v led in series with the diode to the battery of 3v the led will glow if the diode is connected in forward bias in circuit and it doesn't glow if the diode is connected in reverse bias in circuit /diode is damaged . A: a diode will conduct from cathode [negative ] to anode [positive] A stripe at one end is the cathode or a stripe on the arrow is the cathode. By applying the proper voltage it will conduct and show low resistance and a voltage from .6v to .7v. Reversing the lead it will show relatively hi resistance.
What is a terminal user?
A terminal user is the same thing as an end user, a person using a computer.
