Question
For the circuit shown below, in the branch of the circuit containing the capacitor and the ammeter, the resistance is small enough to ignore. Assume that the switch S is suddenly closed after having been open for a long time. Immediately after closing the switch, what will be the direction of the current in the ammeter? From a to b. From b to a. Since there is not a complete circuit in that branch, the current in the ammeter will be zero. After being closed for a long time, the switch S is suddenly opened. Immediately after opening the switch, what will be the direction of the current in the ammeter? From a to b. Since there is not a complete circuit in that branch, the current in the ammeter will be zero; besides, the battery is no longer connected to the circuit. From b to a.Explanation / Answer
a.from a to b ( battery supplies current b.from b to a( capacitor supplies curremnt
