UNIVERSITY OF CALIFORNIA BERKELEY EE100 Summer 2008 Lab 3 Capacitors and Inductors Lab Report Name Name TA Section This write up follows along with the Hands On section of the lab You should complete this report as you do the lab exercises 1 Are you able to measure the value of the resistor If not explain the reason why you cannot make the measurement Explain how the DMM works 2 Explain how you got your ohmmeter reading for the circuit in Figure 4 Why does it take some time before the ohmmeter s reading stabilizes 3 Can you determine the RC circuit configuration series or parallel using an ohmmeter If so how 4 Which box contains a series RC circuit Which box contains a parallel RC circuit Series RC Circuit Black Box 5 What is the time constant 1 Also measure and record RX1 6 What is the time constant 2 Also measure and record RX2 7 Find the resistance and capacitance RB and CB Ask your TA for the resistance and capacitance of the resistor and the capacitor inside the black box Are they in good agreement with the values you have obtained experimentally Explain if there is are any significant difference s Parallel RC Circuit Black Box 8 What is the value of the resistor RB inside the black box 9 What is the time constant of the circuit with Rx What is the value of the capacitor inside the black box Ask your TA for the values of the resistor and the capacitor inside the black box Are they in good agreement with the values you have obtained experimentally Explain if there is are any significant differences 4 Capacitors vs Inductors 10 Time shift Period Calculated phase shift Directly measured phase shift Explain the phase shift 1 5 MHz graph 11 What happens as you increase the input frequency What happens as you decrease the input frequency 6 MHz graph 100 KHz graph 12 Time shift Period Calculated phase shift Directly measured phase shift Explain the phase shift 5 KHz graph 13 What happens as you increase the input frequency What happens as you decrease the input frequency 25 KHz graph 2 KHz graph 14 Explain why the circuit in Question 11 behaved differently than the circuit in Question 12 Using the corresponding graphs with the capacitor and with the inductor as a basis explain the differences between how capacitors and inductors react to time varying input voltages
