Automobile Intermittent Wiper System#
The timing device in an automobile’s intermittent wiper system is based on an \(RC\) time constant and utilizes a \({{ params_C }}\rm\ \mu F\) capacitor and a variable resistor. Over what range must \(R\) be made to vary to achieve time constants from \({{ params_t1 }}\rm\ s\) to \({{ params_t2 }}\rm\ s\)?
Part 1#
What must be the value of \(R\) for the time constant to be \({{ params_t1 }}\rm\ s\)?
Answer Section#
Please enter in a numeric value in \(\rm\ \Omega\).
Part 2#
What must be the value of \(R\) for the time constant to be \({{ params_t2 }}\rm\ s\)?
Answer Section#
Please enter in a numeric value in \(\rm\ \Omega\).
