View the content: DC Circuits Containing Resistors and Capacitors

 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.
