Presentation Transcript

  1. Circuit Lab. Experiment-4 Measurement of Time Constant, Rise Time, Step Response of a RC Circuit

  2. Quiz • A(t)=A.e-t/a • B(t)=B.(1-e-t/a) • Draw the graphic of A(t) and B(t) signals. • For t=a calculate A(t) and B(t)

  3. RC Circuit

  4. Theory • Time Constant t=RC • Rise Tİme tr = (2.2)RC=(2.2)t

  5. Measurement Setup-1 GDS-1102 10 Hz TTL SFG-2120 1 kW +5V 1 mF 0V Rise Time=......... Time Constant=.........

  6. Measurement Setup-2 GDS-1102 10 Hz TTL SFG-2120 10 kW +5V 1 mF 0V Rise Time=......... Time Constant=.........

  7. Measurement Setup-3 GDS-1102 10 Hz TTL SFG-2120 1 kW +5V 1 kW 1 mF 0V Rise Time= ? Time Constant=?

  8. Measurement Setup-4 GDS-1102 10 Hz TTL SFG-2120 +5V 1 mF 1 kW 0V Oscilloscope Screen ?

  9. Final Setup 1 kW +5V 1 kW 1 mF Measure DC voltage across the capacitor using UT33A autorange multimeter

  10. For a DC Voltage applied to capacitor with Vc(0)=0 initial condition; t0+ Capacitor Voltage: 0 Capacitor Current: Max. (Short Circuit) (Capacitor Charging) t>>t Capacitor Voltage: Max. Capacitor Current: 0 (Open Circuit) (Capacitor Charged)
