69 = - (1 / slope) = Results: The value of time constant measured = __________________ sec The value of time constant calculated = ___________________ sec Part B: Measurement of time constant for charging of capacitor Table 2 Rest position of spot on scale =___________________ S No Charging time t (sec) First throw position X (cm) 1 0 2 5 3 10 4 15 5 20 6 25 7 30 8 35 9 40 10 45 11 50 12 55 13 60 14 65 15 70 Calculations: Plot the graph X vs. t and fit a smooth curve. Draw an asymptote to the graph for large values of t. Estimate the asymptotic value X o for X for large values of t. From the graph estimate the time at which X = X o (1- e -1 ) = 0.63 X o . This time is an estimate of the charging time constant = R 1 C. Explicitly Show the procedure on the graph. Results: 1. Estimated value of time constant = _______________ 2. Calculated value of time constant = R 1 C = ______________ ( Two graph papers required) .
