3. An electrical circuit contains a capacitor of105 picofarads and a resistor of 1518 ohms. If thecapacitor is fully charged, and then the voltage is interrupted, inhow much time will about 95% of its charge be transferred to theresistor? Show your calculations.
4. Referring to Question 3 above, if the resistor is a piece ofsome unknown substance 15.18 meters long with a cross-sectionalarea of one square meter, is that substance likely to be aconductor, semiconductor, or insulator? Show your calculations, andexplain your reasoning.
5. If your cell phone has a battery that can hold1518 milliampere-hours of charge, how long will the phonecontinuously operate if it draws 3.5 volts? If necessary,realistically estimate the wattage at which your phone operates –cite any references you use. Show your calculations.
