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.
Voltmeter DMM or VOM has the higher loading effect?
The VOM has the higher loading effect, because it has a lower impedance. It is typical for a VOM to have an impedance of 20K ohms per volt while the DMM has a fixed impedance of 10M ohms or 20M ohms.

How does the loading effect of a voltmeter in a high-rsistance circuit compare to the loading effect in a low-resistance circult?
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.

How you can minimize the loading effect on voltmeter?
To minimize the loading effect on a voltmeter, use a voltmeter with a high input impedance. This will ensure that the voltmeter draws as little current as possible from the circuit being measured, reducing the impact on the voltage being measured. Additionally, connecting the voltmeter in parallel with the circuit, rather than in series, can also help minimize the loading effect.

Why do you get different results when calculating the voltage drop across a resistor and ignoring resistance of a voltmeter and when considering it?
Voltage drop is the product of current and resistance. When you connect a voltmeter across a resistor, you are connecting that voltmeter's internal resistance in parallel with that resistor. The resulting resistance of this parallel combination is lowerthan that of the resistor. As a result the voltage drop (current times this lower resistance) will be lower than it would be without the voltmeter connected. This is called the 'loading effect' of that voltmeter.The higher the internal resistance of the voltmeter, the less effect it will have on lowering the overall resistance when connected across a resistor. This is why the internal resistance of a voltmeter is made deliberately very high. Under most circumstances, therefore, a conventional voltmeter will have very little effect on the resistance of the circuit being tested and, so, it will have no significant effect on the voltage appearing across the resistor.However... for circuits that already have exceptionally-high resistance values, you must be careful when you select a voltmeter as you must take into account its internal resistance and ensure the voltmeter you use has the very highest internal resistance available. This is because the loading effect increases with circuits that have a high resistance. That might involve selecting a voltmeter that works on a completely-different principle , such as an electrostatic voltmeter or, perhaps, an oscilloscope
What is meter loading effect?
Meter loading effect refers to the influence that a measuring device (like a voltmeter or ammeter) has on the circuit it is measuring. When a meter is connected, it can draw current or alter voltage, thereby affecting the original conditions of the circuit. This effect can lead to inaccurate measurements, especially in high-impedance circuits, where the meter's internal resistance might significantly impact the circuit's behavior. To mitigate this, high-impedance meters are often used to minimize the loading effect.
How does the loading effect of an ammeter in a low resistance circuit compare to the loading effect in a high resistance circuit?
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.

How can loading effect affect voltage measurement in a circuit?
Suppose you have two 100 kilo Ohm resistors in series across a 12 volt supply.The expected and actual voltage at their junction is 6 volts. Now measure the voltage across one resistor with a Voltmeter. The instrument must take a little power to move the meter needle or be taken by the digital circuitry. If the input resistance of the voltmeter is 100 Kilo Ohms then it will make that resistor under test appear to be 50 Kilo Ohms. The voltage across the resistor drops to 4 Volts. This is the loading effect of the voltmeter.

What is the effect of pressure on the state of matter Explain with an example?
At a high pressure a gas can be transformed in a liquid and water vapors is an example.
Is loading effect more when load impedance is less then source impedance?
The higher the mismatch between the load impedance and source impedance, the higher the loading effect.
