Objectives Learn how to construct RC circuits. Learn the function of a capacitor. Study the theory of RC circuits.
Summary This laboratory will be the first time we’ll construct a circuit with a capacitor connected in series with a resistor and a voltage source (RC circuit). In this laboratory we measured the capacitor’s voltage from 5 seconds to 120 seconds (The voltage is 0v in 0 seconds). We measured the voltage in the capacitor 3 times. Before each time the capacitor needed to be discharge in parallel to a resistance and we also measure the drop of voltage in the capacitor 3 times.

Part A: In this part of the laboratory we have to construct the circuit shown below and fill table-1 that consists in measure different values. Like The voltage, current, power in the F μ 1000 capacitor and in the K 8 . 6 resistance. These values are for the charging.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
