Wire up the circuit as shown below (Figure 1). You will now measure a discharge curve for your 470uF capacitor. Charge the capacitor to 15V. How long will it take? Can you measure the time? Then discharge it by disconnecting one of the poles of the voltage source. Take measurements of the voltage across the resistor every 15 seconds for 4-5 minutes. Draw a neat diagram where the voltage is a function of time, i.e. u(t) on the y-axis and t on the x-axis. Check that the curve is correct by calculating u(t), which should be about 0.37U. If not, what is the reason? Calculate the true value of the capacitor, using your diagram. With the help of my DAQ and NI ELVI smx Instrument Launcher. How are the cables connected on the breadboard?
