PRELIMINARY EXERCISE Important Note: You are required to do this exercise BEFORE the lab session. a. Explain what is loading effect in measurement. b. Draw the connection using the potentionmeter shown in Figure(i) as a voltage divider. c. The resistance value in Figure (i) are R₁ = 5 k2, R₂-5 k2 and R, -5 k2 respectively. Calculate the error of Moving Coil Meter if it has internal resistance 10 k2 and voltage supply (Vs) is 10V. m Figure (i) d. Discuss the error in voltage measurement between low and high resistance circuit. e. Briefly discuss the difference between a logarithnm and linear track. f. Explain the input and output impedance of buffer circuit. What are the functions of buffer in instrumentation and measurement.
