Laboratory #13: RC-Circuit Purpose and Introduction
Electrical circuits are used throughout everyday life. In the RC-Circuit experiment, the student views the charge and voltage of resistors and capacitors. The student will need the following supplies: power supply, stopwatch, banana plug wires, resistor, computer for data analysis, alligator clips, and a capacitor. The charging capacitor experiences a charge erect over time while connected to the capacitor. The voltage that comes through the capacitor also rises with the capacitor, being that voltage is relative to charge [1]. The time constant is the time needed for the charge of the capacitor to reach at least 63% [1]. To show this in an equation: t=1s. Capacitors are not constant in the rate which they charge or discharge [1]. However if the amount of charge along the capacitor is higher it will determine how much time is taken for it to charge and discharge. Ideally the charging behavior equation will resemble the following: Q ( t )= CV 0 ( 1 e t / RC ) (1) The Q and T involved in the above equation represents the charge happening to the capacitor and time. The C is the capacitance when conjoined with resistance, while V voltage from the power source. Voltage correlates to the charge of a capacitor so (V=Q/C). The following equation is an expression for the voltage that is distributed along the capacitor in relation to time: V ( t )= V 0 e t / RC (2) Experimental Details To determine the resistance of the resistor provided for the experiment, a multimeter was used and the color code was recorded. The figure below depicts the set up for this experiment.
