A 500- resistor, an uncharged 1.50-F capacitor, and a 6.16-V emf are connected in series.
What is the initial current?
What is the time constant?
What is the current after one time constant?
What is the voltage on the capacitor after one time constant?
The timing device in an automobile’s intermittent wiper system is based on an time constant and utilizes a 0.500-μF capacitor and a variable resistor. Over what range must be made to vary to achieve time constants from 2.00 to 15.0 s?
If you wish to take a picture of a bullet traveling at 500 m/s, then a very brief flash of light produced by an discharge through a flash tube can limit blurring. Assuming 1.00 mm of motion during one constant is acceptable, and given that the flash is driven by a 600- capacitor, what is the resistance in the flash tube?
