A 10 V emf battery is connected in series with the following: a 2 microfarad capacitor, a 2 ohm resistor, an ammeter, and a capacitor. After the switch has been closed for a relatively long period (several seconds, say), what are the current and capacitor voltage readings, respectively? 1 2 3 4 25% 25% 25% 25% 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 1. zero A, 10 V 2. zero A, zero V 3. 5 A, zero V 4. 5 A, 10 V
