A digital voltmeter will read negative voltage, if connecting backward.

If the meter is an analogue type, the needle will go backwards and dip below the 0 on the scale.

What type of meter would be connected on both sides of a resistor in a circuit?

ammeter in series at any side as required since it is bilateral and voltmeter is connected in parallel to measure voltage drop across it


What would happen if a voltmeter were substituted for an ammeter?

Smoke. Since a voltmeter is in parallel with the load it is right across the source voltage. Putting the amp meter across the line with its low resistance it will act like a fuse, hence the smoke. Newer solid state testers are usually smarter that the operators. They have built in circuitry which sense the wrong settings you are using and shut the tester off with a "beep" to let you know that you are doing something wrong.


What is loading affect of multimeter?

'Loading effect' applies to voltmeters, or to multimeters when set to measure voltage. It describes the change in a circuit's resistance when the resistance of the voltmeter is taken into account. It's effect is to cause the resulting measuredvoltage to be different from the actual voltage which would appear without the voltmeter connected. The loading effect is minimised by ensuring that the internal resistance of the voltmeter is significantly higher than the resistance of that part of the circuit to which it is connected. For general voltage measurement, this is usually the case anyway, but when measuring circuits which, themselves, have very high resistance care must be taken over the choice of voltmeter to be used.

Why voltmeter should have a very high resistance?

well a voltmeter measures AC and DC voltage. resistance is a term used only for DC voltage, A voltmeter uses a term called Impedance for AC, without it, when you measure across two terminals it would create a short circuit and would blow up the meter. it is basically a safety feature to prevent people from creating short circuits when measuring.

A voltmeter is connected to the terminals of a battery that has emf 12.0V and internal resistance 3.00 ohms The battery is not connected to any other external circuitry What is the vmeter's reading?

The voltmeter would read 12 volts. An ammeter connected to to battery would only read 4 amps (12 volts divided by 3 ohms =4)


How would you connect a voltmeter?

A: It must be connected across the device ammeters cannot measure DC current directly


How can a voltmeter be connected in parallel to measure the voltage across a circuit component?

To measure the voltage across a circuit component using a voltmeter, you would connect the voltmeter in parallel with the component. This means that you would connect one lead of the voltmeter to one end of the component and the other lead to the other end. This allows the voltmeter to measure the voltage difference between the two points, giving you the voltage across the component.

How can a voltmeter be connected in parallel to a circuit to measure the voltage across a specific component?

To measure the voltage across a specific component in a circuit using a voltmeter, you would connect the voltmeter in parallel with the component. This means connecting the positive lead of the voltmeter to the point before the component and the negative lead to the point after the component. This allows the voltmeter to measure the voltage difference across the component accurately.

What is a sentence for voltmeter?

A voltmeter is a device used to measure the voltage in an electrical circuit. An example sentence would be: She went to the hardware store to purchase a voltmeter.


Is it possible to apply voltmeter across a variable resistor?

Of course. A good voltmeter can be applied across anything, since its impedance is high and its presence has no effect on the operation of the circuit. When it's connected across a variable resistor, the voltmeter most likely reveals a changing voltage as the resistor is varied.
