A 500- resistor, an uncharged 1.50- 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?
