Day 16 RC Circuit

Quantitative Measurement on RC System: 

For this experiment, we were asked to create RC circuit with a resistor with resistor, power supply, and capacitor. We used logger pro to measure the voltage, and before we also make some prediction that the potential voltage and time should be inversely related. As the result below, we were right.

On discharge(pink) one, we know that B in the natural exponential equation should be vary close to zero. However, the Amp should be close to 4.5 V (original V from power supply). For conclusion, C as our charge time should be the same for both discharge and charge.

To be able to find out the C value which is 0.003620 sec by theoretically method. We first used multimeter to determine the resistance of our resistor. (R = 2.15 k"omega") 

We next used their relationship that Time =1/Resistance*Capacitance to solve the value of charge time. 

As the result, t=0.00465 sec, it mean there were about 22% error. This error might come from the capacitors value straight off the labeling. Below is our calculation.
