Why placing the ammeter between the potential divider and the voltmeter will give an incorrect value?

beacause ammeter is use to measure the current not to measure the voltage

Why is the voltmeter connected in parallel but the ammeter connected in series?
The Voltmeter is used to measure the electrical potential difference between two points... so it's no use to connect it in Series , because the electrical potential difference between two points at the same line is zero ==> the readings will always be zero. The Ammeter is used to measure the electric current in a circuit... so it's no use to connect it in Parallel , because you want to know the current flowing in this wire. note the internal Resistance of the Ammeter is very little and very high for the Voltmeter --> so they will not affect the circuit.
An ammeter is used for what?
An ammeter is an instrument which is used for measurement of current flowing in any circuit
What is used to measure the difference in electrical potential between two points in a circuit?
voltmeter
What is the function of voltmeter?
for measurement of potential between two points.It is connected in parellal with the two points.
Which meter measures the potential difference in the circuit?
A voltmeter measures the potential difference between two points,whether or not the two points are in the same circuit.
Why ammeter connects in series and voltmeter in parallel in electric circuit?
Because the ammeter measures the current flowing THROUGH the wire, butthe voltmeter only measures the potential difference between two points.
Difference between galvanometer and voltmeter?
Galvanometer is similiar to ammeter which is used to detect small current through it whereas a voltmeter measures the potential difference in a cicuit..

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.
Uses of voltmeter?
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
An ammeter is used for what?
An ammeter is an instrument which is used for measurement of current flowing in any 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.
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).
What is the difference between a volt meter and a am-meter?
A voltmeter measures the difference in potential between two points on a circuit. An ammeter measures the amount of current passing through a point in a circuit. Although you often see them packaged together in a tool called a multimeter, they measure different quantities: Voltage, also known as potential difference, measured in volts, and Current, measured in amperes, or just amps. Also, they're used in somewhat different ways: -- The voltmeter simply touches the two points in the circuit between which the voltage is measured. -- The ammeter has the circuit current flowing through it. That means the circuit must be broken briefly, and the ammeter connected into the 'hole', before the current can be measured. (There are instruments that are exceptions, but they're rather specialized. The statement above holds generally true for the common ammeter.)
