Unformatted text preview: Date: _10/05/2007 _ Physics 211L RC and RL circuits Name: _Sarah Karam _ Section number: _-1-_ Partners Name: _Haitham Shoaib _ Instructor: _Ms. Sarah Najm _ A- RC: RC time for 330 F capacitor and 100 resistor: Beginning time (s) Time to half value of max. voltage (s) t /1/2 (s) 0.4876 0.5128 0.0252 0.4878 0.5114 0.0236 0.4878 0.5112 0.0234 0.479 0.5116 0.0326 0.477 0.5118 0.0348 Deduce the RC time of the circuit along with its rms value. 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 = c ln2 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 = 2.41 10-3 s = t 1/2 = 0.028 0.002 c =RC=330 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 F Q=CV= 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)...
