The smallest value which can be measured by the measuring instrument is called its least count. All the readings values or measured values are good only up to this value. The least count error that is associated with the resolution of the instrument.
For example, a vernier callipers scale has the least count as 0.01 cm; a spherometer may have a least count value of 0.001 cm. Physics Assignment Help could show that Least count error value belongs to the category of random errors but within a limited size of error; it occurs with both systematic and random errors. If we use a metre scale for measurement of length value, it may have graduations at 1 mm division scale spacing or interval.
Using instruments of higher precision or quality, improving experimental techniques, etc., we could reduce the least count error. Repeating the observations many times and taking the arithmetic mean of all the observations, the mean value could be very close to the true value of the measured quantity.
Personal error which arise due to an individual’s bias, lack of proper setting of the apparatus or individuals carelessness in making observations without observing proper precautions, etc. Physics assignment help give example that , if you, by habit, always hold your head and eye a bit too far to the right while reading the position of a needle on the scale, you will introduce an error due to parallax.
Systematic errors could be minimised by improving experimental techniques, selecting better instruments and tools and removing personal bias as far as possible. For a given set-up, these errors may be estimated to a certain given extent and the necessary corrections may be applied to the readings.
Physics assignment help provide better solution for assignment problems within deadline. Importances of Physics assignment help increase with level of education and complexity and quality of solution. Physics assignment help provide timely solution for all level of students.
