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 110 µf 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 1.70 s?

Resistance, R = 8624.18 ohms

Explanation:

It is given that,

The emf of the circuit,

Capacitance of the capacitor,

Voltage across the capacitor, V = 10 V

Time for which the wipers are to operate. The formula for the voltage across the voltage is given by :

So, the value of resistance used in the charging circuit is 8624.18 ohms. Hence, this is the required solution.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
