How do you connect a digital voltmeter to a battery?
Use a multimeter that has both scales on it . All you need to do is change the scale from AC to DC

When the resistance in all four are equal
What is voltmeter sensitivity?
Voltmeters are connected in parallel with the components whose voltage or voltage drop you want to measure. That means that the internal voltmeter's resistance will create a new branch in parallel with the component, thus increasing the current in the circuit. If there are other components in series with the component to which the voltmeter is connected, this increment of current will increase the voltage drop across them, reducing the voltage drop across the component whose voltage is being measured. This is obviously an induced error in the measurement, which adds up to other errors built into the voltmeter (accuracy, resolution, linearity, parallax, etc.) When measuring the output voltage of low resistance (high current) power supplies, the input impedance is usually not an issue. However, when measuring a low current power supply, the input resistance of the voltmeter will have to be at least 10 times the internal resistance of the power supply. Otherwise, the error will be too noticeable. Therefore, the ideal voltmeter should have an infinite internal resistance. Since this is not the case, it should at least have several megohms. Analog voltmeters usually have s sensitivity of 20 to 30 kilohm per volt (kΩ/V), which varies withe the voltmeter range setting. Digital voltmeters, instead, have constant high (>20 megohms) input impedance, which is a combination of pure resistance and reactance, usually capacitive, regardless of the voltage range. That is why the specs of a digital voltmeter always indicate the input capacitance.
What should be the resistance of an ideal voltmeter?
infinity- so that all the voltage is measured across the component instead of losing some in voltometer circuitry
What are electronic and mechanical equipment called?
Digital circuits are the most common physical representation of Boolean algebra and are the basis of all digital computers. Computer's industrial processes are constructed of digital circuits.
What are the difference between a multimeter and a voltmeter?
A multimeter measures electrical properties such as AC or DC voltage, current, and resistance. Rather than have separate meters, a multimeter combines a voltmeter, an ammeter, and an ohmmeter. The two main kinds of a multimeter are analog and digital. A voltmeter measures the potential difference (voltage) between two points. the voltmeter only measures volts.
A digital voltmeter is connected to the poles of a 4.5 v-batterywhat will be the display of this voltmeter if the connection was made with a wrong polarity?
It will still be 4.5V except your meter will either indicate "-" for negative or normally no indication at all for positive. If your meter indicates both negative and positive, you will see "+".
What car is fastest of all.?

What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
Boolean logic gates are combined what type of packages?
All packages. Everything digital is boolean logic.
What happens if you accidentally connect the positive lead of a voltmeter to the negative terminal of a 1.5 volt battery and the negative lead to the positive terminal?
Voltmeter will give you opposite readings or will not work at all.
Is a desktop computer a type of analog computer?
No, your desktop computer is a digital computer as are virtually all modern computers.
Is a digital telephone the same thing as a cell phone?
Digital phone signifies the dialing method in a particular phone. The dialing method can be digital or analog. The house phone can be digital, where you press buttons to dial a number or in rare case analog type where in you turn a number on a dial. All cell phones are digital.
What breed is the fatest horse in the world?
thoroughbreds It depends on the distance. A quarter horse will outrun a thoroughbred in the 1/4 miles, but after that, it's all thoroughbred.
How long have digital cameras been around?
The first ever digital camera was invented in 1975 by engineer at Eastman Kodak called Steve Sasson. It was an unwieldy invention, the lens from a Super 8 movie camera, a digital cassette recorder and 16 nickel cadmium batteries! Together with hacked pieces from a voltmeter and an all new charged coupled device imaging array (CCD) it weighed a whopping 8lbs and took 23 seconds to produce the first ever digital image!
When a Wheatstone bridge is in a balanced condition the center voltmeter in the bridge?
When the resistance in all four are equal
