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 = 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 resistor: Beginning time (s) Time to half value of max. voltage (s) t /1/2 (s) 0.4726 0.5038 0.0312 0.4652 0.504 0.0388 0.4732 0.5038 0.0306 0.4672 0.5034 0.0362 0.4692 0.5044 0.0352 Deduce the RC time of the circuit along with its rms value. How does this value agree
