The time constant of a resistive/capacitive circuit is defined as:
The product tC (time x capacitance) |
||
Time divided by RC (time/(resistance x capacitance)) |
||
The product VI (voltage x current) |
||
The product RC (resistance x capacitance) |
The function generator will be used to generate a square wave which will:
Create a force on the resistor |
||
Charge and discharge the capacitor through the resistor |
||
Allow a graph to be produced on the computer |
||
Be converted to a sine wave through inductance |
There are two statistical analysis requirements in this experiment. They are:
Calculate % difference and relative uncertainty of the function generator |
||
Calculate the resistor and capacitor tolerance |
||
Compare the calculated tolerances of the resistor and capacitor and compare to the % difference, and calculate the % uncertainty due to scope measurement error |
||
Calculate the standard deviation of the scope timescale and the voltage probe readings |
||
A small time constant of an RC circuit means
the resistor will store more charge than the capacitor |
||
the capacitor will discharge slow |
||
the capacitor will discharge fast |
||
none of the above |

Background Summary Questions: 1. What does the time constant of an RC circuit that is being charged tell you? 2. What does the time constant of an RC circuit that is being discharged tell you? 3. How is the voltage across the capacitor related to the charge on a capacitor? (Linear, Inverse, Quadratic, etc.) 4. Based on your answer to question 3, how would you write an expression for the voltage across the capacitor as a function of time? a. Charging: V(t) b. Discharging: V(t)= Background: The...
A full-wave diode rectifier supplies a 30Ω resistive load from a 400Hz, 110V single-phase AC supply. A capacitor is connected in parallel with the load. Calculate the capacitance required if the maximum peak-to-peak voltage ripple across the resistor is to be restricted to 10V. You may assume that the RC product of the resistance and capacitance will be significantly greater than the period of the AC waveform. State any other assumptions made.
A simply RC circuit made up of a capacitor with capacitance C and resistor with resistance R = 15 kΩ is attached to a battery with emf E = 24 V. If time constant is 25 µs, what is the capacitance C and the time it takes for the voltage across the capacitor to reach 16 V after the switch is closed at t = 0?
8. Capacitance in circuits, RC circuits When a voltage source Vo is applied to a capacitor in a circuit which has a resistance R, a charge Q CV will build up across the capacitor. This does not happen instantaneously, but takes some time. The charge builds up exponentially with a characteristic time r = RC. Charging: V = v. 1 - e-t/RC) Discharging: Vc = V e-t/RC Page 2 of 3 When t = RC , the exponential is lle,...

5. Using the values of the capacitance and resistance you have set, calculate the time constant, T. 6. You may set the voltage of the battery in the same way you set the values for the capacitor and resista The default is 5.0V. Any value between 5.0V and 12.0V would be fine. 7.
