NUC 255 M3Al Problem Set #5 l. A capacitance C discharges through a resistance R. Dene and give an expression for the time constant. To attain a long time constant, do we need large or small values for R? For C? (20 points) 2. Using the circuit shown below, calculate the time constant for the circuit and sketch the voltage response as the capacitor is charged. (20 points) 3:0 R=100k + + 0c\") 05:100V C={}.01,uF 3. A person shuffling across a dry carpet can be approximately modeled as a charged lOO-pF capacitance with one end grounded. If the person touches a grounded metallic object such as a water faucet, the capacitance is discharged and the person experiences a brief shock. Typically, the capacitance may be charged to 20,000 V and the resistance (mainly of one's nger) is 1009. Determine the peak current during discharge and the time constant of the current. (20 points) 4. List the steps for a dc steady-state analysis of RLC circuits. (20 points)
