(a) A 3.0 K ohms resistor is connected in series with a capacitor at time T=0. Its fully charged and at a voltage of 24V. What is the time constant of this circuit?
(b) what would be the current through the resistor after 1.0 micro seconds.
(c) This resistor powers a tiny device that needs a minimum of .05 W to run the device. How long will the capacitor be able to run the device? (hint: what would be the minimum voltage needed to be across the resistor)
