When a battery is connected across a capacitor, the charges on the plates are always equal and opposite, even for plates of different size.
Text Solution
Verified by ExpertsThe correct answer is:
A
Statement: When a battery is connected across a capacitor, the charges on the plates are always equal and opposite, even for plates of different size.
Explanation:
1. When a capacitor is connected across a battery, one plate gets positively charged while the other plate gets negatively charged. This arrangement is governed by the law of conservation of charge.
2. The total charge drawn from the battery must be equal to the charge stored on the capacitor plates, which ensures that the charges are equal in magnitude.
3. Regardless of the physical size of the plates (as long as the plates are part of the same capacitor), the charge on one plate is +Q and the charge on the other plate is -Q. Therefore, the charges are always equal and opposite, satisfying the condition stated.
Conclusion: Thus, the statement is true.
