The capacitor is originally charged. How does the current I in the ammeter behave as a function of time after the switch is closed? 1. I = 0 always.

2. I = constant, not equal to 0.

3. I increases, then is constant.

4. I instantly jumps up, then slowly decreases.

5. None of the above.

The current in the ammeter is zero.

(1) is correct option.

Explanation:

Given that,

The capacitor is charged.

We need find the current after closed switched

We know that,

When switch is closed then the capacitor behave as a short circuit, and the all current flows through it. the current is zero.

Then, the ammeter reads zero.

Hence, The current in the ammeter is zero.

(1) is correct option.
