Lab 7 PHYS 159
Gina Sengeri 91733139 and Pauline Gamallo 30835482
Objective:
Measure the capacitance of one capacitor.
Clarify Objective:
● The capacitor is a device consisting of two conductors in close proximity and
insulated from each other that stores energy. The capacitance of a capacitor
determines how much energy can be stored.
● Capacitance is the ratio of the amount of electric charge stored on a conductor to a
difference in electric potential.
Capacitance is a fixed quantity that has a known mathematical relationship with charge, time
and resistance. We will use this mathematical relationship to determine the capacitance.
The relationship is:
V(t) = V*(1-e^(t/RC))
Procedure: (edits in red)
1. Measure the resistance of the four resistors you have been provided with using a
multimeter
2. You will use 6 combinations of resistors, starting from 10000 to 60000, in increments
of 100000 kilo ohms.
3. Set up your RC circuit shown below. It is shown here above, taken from the previous
lab.
4. Connect the circuit to the oscilloscope and the function generator, using two coaxial
cables ( shown in image below)
5. Set up your oscilloscope connected to the circuit
