The loading effect in measurement refers to the alteration of the quantity being measured due to the act of measuring it. This effect occurs when the instrument used to measure the quantity draws current or energy from the circuit under test, thereby affecting the circuit's performance. It can lead to inaccuracies in measurements, especially in circuits with high impedance. To minimize the loading effect, it is important to use measurement instruments with high input impedance.

'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.
loading of an ammeter in a circuit decreases the flow of current,so it has to be calculated to reduce expected errors in the operations
Kindle help me to answer What is valve point loading effect and its applcation

The higher the mismatch between the load impedance and source impedance, the higher the loading effect.

Yes, you have to use an op-amp buffer to prevent the loading effect.
The loading effect can affect voltage measurement in a circuit by causing a decrease in the measured voltage due to the current drawn by the measurement instrument altering the voltage across the circuit elements. This can lead to inaccuracies in the voltage measurement as the presence of the measuring device changes the current flow and voltage distribution within the circuit. To minimize this effect, high input impedance voltmeters should be used in voltage measurements.

It does effect the measurement, but on an extremely low level. You could as well say it doesn't effect it.
