Compare your result to the value deduced from the “marked” values of C and R. The average value of 1/2 (0.0252+0.0236+0.0234+0.0326+0.0348) t = =0.02792 s 5 Using the following equation: t 1/2 = τ c ln2 τ c = t 1/2 /ln2= 0.04s (experimental) N x x i ∑ = = 0.02792 s x x d i i- = ) ( 1 2- = ∑ N N d i α = 2.41 × 10-3 s = t 1/2 = 0.028 ± 0.002 τ c =RC=330 μ F *100 Ω = 0.033s (theoretical) 0.04 + 0.01 = 0.05 0.04 – 0.01 = 0.03 0.033 is between 0.03 and 0.05 which implies that the measurement is accurate. 1 Grade: What is the maximum charge that can be stored in the capacitor? Maximum charge is obtained when the voltage is maximum. V max = 4v C= 330 μ F Q=C×V= 330 × 4= 1.32 ×10-3 C RC time for two capacitors in parallel and the 100 Ω resistor: Beginning time (s) Time to half value of max. voltage (s) t /1/2 (s) 0.4726 0.5038 0.03120....
