A voltmeter is used to measure potential difference across two points in an electrical circuit .
The voltmeter is connected in parallel across the circuit element (resistance ) so that its inclusion in the circuit has negligible effect on total resistance and current flowing in yhe circuit
A voltmeter has high resistance,if connected in series it will increase of circuit and reduce the current in the circuit

∙ 10y agoA voltmeter displays the potential difference (voltage) between two points.
It makes no difference what kind of circuit the two points are part of.

Can you use 2 20amp circuit breakers to protect to 40amp?
yes, you can use but connect in parallel mode.
What instrument measures electrical pressure in a circuit?
A voltmeter
What kind of circuit is a power bar?
a parallel circuit
What instrument measures a circuit that is sensitive to loading?
A high-impedance voltmeter is most appropriate.
Type of circuit that is used in house wiring?
Both series and parallel circuits are used What_types_of_circuits_are_used_in_homes. If the circuit is a dedicated circuit which means that there is only one device in the circuit, then it is a series circuit. All the rest will be classed as parallel circuits.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
What are two familiar mistakes when using an ohmmeter and a voltmeter?
Voltmeter connect in parallel with the circuit setting on voltmeter highest range first then to lower range. Ohmmeter we need to use the ohmmeter meter setting connect across the resistor
How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
What is the function of the voltmeter in an electric circuit?
A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
Describe the proper placement of a voltmeter in a circuit?
A voltmeter should be connected in a parallel connection
Is the voltmeter always connected in series to the circuit?
in parallel
Where ammeter and voltmeter are put in circuit?
Place in parallel anywhere in the circuit. One lead goes to the hot, the other to the neutral.
How can you say that ammeter measures current and voltmeter measures voltage?
voltmeter in parallel and ammeter in series of a circuit.
Is a voltmeter placed parallel to a circuit?
Depends. What did you want to measure? If it's voltage drop across the incandescent element, then you had better hook up your infinite resistance voltmeter in parallel with the lamp.
How do you connect a voltmeter to a battery?
To measure the total emf simply connect the battery and voltmeter with the right terminals , but to measure the terminal potential difference which is less than the emf the voltmeter is connected in parallel with the battery
Why is a voltmeter not placed inside the circuit?
The voltmeter is connected parallel to the circuit in order to measure the voltage drop across that circuit or sub-circuit. If you were to connect the volmeter series to the circuit, since it is a high impedance device, it would represent an effective open-circuit condition. You would see the voltage available to the circuit, but the circuit would not receive its intended current and it would not function. Contrast this with the ammeter, which you do place series to the circuit in order to measure the current flow through the circuit.
How is a voltmeter connected in the circuit to measure the potential difference between two points?
The voltmeter is connected in parallel between the two points whose potential difference is required.
