Aim of the experiment: This experiment will consist of utilizing an
oscilloscope in order to determine a time constant of the capacitor. We
will compare this value to the theoretical value which can be
determined multiplying the value of the resistor and the capacitor.
Theory – Brief Introduction on RC circuit, circuit diagram, time constant
definition: an RC circuit is a simple circuit consisting of a resistor and a
capacitor. The following is a diagram of the circuit:
Time constant is the amount of time it takes for a capacitor to discharge to
36.7% of its original charge while current is travelling through a resistor.

The following figure represents an RC-Circuit with the switch. In Figure A, the
capacitor is initially uncharged. In Figure B, the capacitor is initially fully charged.
1) Draw and label the current direction immediately after the switch is closed for each
figure.
2) Consider Figure A. What is the voltage across the capacitor as t → 0? Explain.
3) Consider Figure B. Is the voltage across the resistor increasing, decreasing or
staying the same as t → 0? Explain.

A capacitor is rated for 250 Vac. Can it be used in a DC circuit? If yes, what is the maximum DC voltage that the capacitor can be connected to?

In the diagram below, the switch S has been closed for a long time. A) What is the output voltage
Vout? What is the charge on the capacitor?
b) The switch is opened, so the output voltage increases. What is the time constant that describes
the charging of the capacitor in terms of R and C?
c) When Vout reaches 10 V, the switch closes and the capacitor begins to discharge. What is the
time constant that describes the discharging in terms of R and C? Hint: Apply Kirchhoff's Rules
to both loops and the sum of the currents at the junction above the capacitor in the diagram, and
use I=dq/dt.
If the switch opens when Vout reaches a lower value, say 5V, the capacitor will charge again, and
thus one can cycle the voltage with a time constant determined by the circuit: this demonstrates
the principle of operation of an electronic timer.

A resistor and a capacitor are connected in series with a variable inductor. When the circuit is connected to a 240 – V, 50 – Hz supply, the maximum current given by varying the inductance is 0.5 A. At this current, the voltage across the capacitor is 250 V. Calculate the values of (a) the resistance, (b) the capacitance, and (c) the inductance.
