In an electric circuit, the final electric current when a capacitor is fully charged
Correct answer: A. Is zero.
- A. Is zero.
- B. Is minimum.
- C. Is maximum.
- D. Cannot be determined.
Explanation
In an electric circuit, when a capacitor is fully charged, it acts as an open circuit. This means that no current flows through the capacitor, making the current zero. Option A is correct because it correctly identifies that the current is zero. Option B is incorrect because 'minimum' still implies some current, which is not the case here. Option C is incorrect because the current is not maximum when the capacitor is fully charged. Option D is incorrect because the current can be determined and is indeed zero.

About Capacitors
Capacitors store electric charge and energy in an electric field between conductors. Work includes capacitance, the relation Q = CV, dielectric materials, charging and discharging, energy formulas, and combinations of capacitors in series and parallel. Electric potential difference is needed to understand why charge and stored energy change.
