Fit parameters Resistor Capacitor Time Percent constantDifference Trial A B 1/C R (2) C (F) RC (s) Discharge1 Charge 1 Discharge2 Charge 2 16820595 0,0006.5 1-600 053 50,000 A. Resistors and capacitors are not marked with their exact values, but only approximate values with a tolerance. Since the resistors were measured, their tolerance values are unimportant. However, the capacitor was not measured. Rather, the marked value of capacitance was used, and a typical tolerance on a capacitor is ± 15%. If there is a discrepancy between the theoretical time constants ( = RC) and the experimental time constants (from the fit parameters), can the capacitor tolerance value explain the difference?

Explanation / Answer

YES CAPACITOR TOLERANCE VALUE CAN EXPLAIN THE DIFFERENCE AS CAPACITORS ARE NOTORIOUSLY INACCURATE.HOWEVER SOME OTHER FACTORS ARE ALSO INVOLVED IN MAKING DIFFERENCE BETWEEN THEORITICAL AND EXPERIMENTAL VALUES. SOME PARASITIC VALUES LIKE RESISTANCE AND INDUCTANCE IN REAL CAPACITORS CAN CAUSE THE DIFFERENCE.
