Name: DC Circuits Containing Resistors and Capacitors
ID: m42363
Language: English (en)
Summary:
  • Explain the importance of the time constant, τ , and calculate the time constant for a given resistance and capacitance.
  • Explain why batteries in a flashlight gradually lose power and the light dims over time.
  • Describe what happens to a graph of the voltage across a capacitor over time as it charges.
  • Explain how a timing circuit works and list some applications.
  • Calculate the necessary speed of a strobe flash needed to “stop” the movement of an object over a particular length.
