Acharging rc circuit controls the intermittent windshield wipers in a car. the emf is 12.0 v. the wipers are triggered when the voltage across the 125 mu or micro f capacitor reaches 10.0 v; then the capacitor is quickly discharged (through a much smaller resistor) and the cycle repeats. what resistance should be used in the charging circuit if the wipers are to operate once every 1.80 s?

Explanation:

We have the following information,

We apply the equation for capacitor charging the voltage across it,

Replacing values,
