The time constant for RC circuits:
We are asked to determine the value of R that gives time-constant between 2.00 s and 15.0 s.
The timing device in an automobile's intermittent wiper system is based on an RC time constant and utilizes a 0.500-μF capacitor and a variable resistor. Over what range must R be made to vary to achieve time constants from 2.00 to 15.0 s?
