What is the Kirchhoff's junction rule equation for this junction? A 10-V-emf battery is connected in series with the following: a 2-mu F capacitor, a 2-Ohm resistor, an ammeter, and a switch, initially open; a voltmeter is connected in parallel across the capacitor. After the switch has been closed for a relatively long period (several seconds, say), what are the current and capacitor voltage readings, respectively? A resistor, inductor, battery, and switch are all hooked up in series. Draw a...
