Why voltmeter and ammeter are connected with reverse polarity?
Voltmeter and ammeter are connected with reverse polarity to ensure accurate readings and prevent damage to the instruments. A voltmeter is designed to measure the potential difference across a component and should be connected in parallel, while an ammeter measures current and is connected in series. Reversing the connections can lead to incorrect measurements, potential circuit damage, or even damage to the measuring devices. Therefore, proper polarity is crucial for both functionality and safety.
When the VOM is to be used as ammeter how should this be connected?
When using a voltmeter (VOM) as an ammeter, it must be connected in series with the circuit. This is because an ammeter measures the current flowing through the circuit, which requires all the current to pass through the device. Additionally, ensure that the voltmeter is set to the appropriate current range to avoid damaging the device. Always take precautions to ensure the circuit is de-energized before making connections.
The electrical meter that should be connected in series with a live circuit is?
ammeter
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
Describe How an ammeter should be connected in a circuit?
An ammeter should be connected in series with the circuit component whose current you want to measure. This ensures that all the current flowing through that component also passes through the ammeter. It is important to connect the ammeter with the correct polarity, observing the positive and negative terminals, to avoid damaging the device. Additionally, the ammeter should have a suitable range for the expected current to ensure accurate readings and prevent overload.
How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
Is a ammeter connected in series or in parallel with the circuit under test?
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged

Should a Voltmeter always be connected in a series with a component?
Voltmeter should be connected always in parallel to a circuit ANSWER : IT should be in parallel except when used to measure current. Then it should be placed in series across a shunt.
What is the difference between ammeters and amp meters?
An Ammeter connects a low impedance on the test points, so the equivalent of that is a "short circuit" between the test points. This is done to avoid a drop of current on the tested circuit. A Voltmeter connects a high impedance on the test points, so the equivalent of that is a "open circuit" between the test points. This is done to avoid a drop of voltage on the tested circuit. --------- In terms of external connections Ammeter (used to measure current) is connected in series of the circuit (through which the current flow need to be measured) and voltmeter (used to measure voltage) is connected in parallel to points in circuit (across which voltage needs to be measured).
Why should ammeter still be connected in a series despite the fact that the bulbs are already connected in parallel?
Because the ammeter connected in parallel will act as a short circuit.
The electrical meter that should be connected in series with a live circuit is?
ammeter
Why is voltmeter is connected in parallel and ammeter in series?
Because its function is to measure the current, i.e. the amount of electrical flow in the circuit, and this require that the current flows through the ammeter A good ammeter has very low series resistance, so connecting it in series will not affect your circuit. Be careful when using an ammeter , because of its very low resistance , it can cause a short circuit if you use it by mistake to measure "voltage", so avoid connecting it in Parallel.
How would you extend the range of a voltmeter and ammeter?
if we would like to expand the range of voltmeter we should change the voltmeter resistance even to be appropriate . we should use a variable resistance to control of its value . I would extend the range of a voltmeter by adding resistance in series with it. I would extend the range of an ammeter by connecting resistance in paerallel with it.
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
