The correct Answer is:
To solve the problem regarding the characteristics of capacitors connected in a parallel network, we will analyze each statement one by one. ### Step-by-Step Solution 1. **Understanding Capacitors in Parallel:** - When capacitors are connected in parallel, they share the same voltage across their terminals. This is a fundamental property of parallel circuits. 2. **Analyzing Statement (I):** - **Statement (I):** "Potential difference across each capacitor is same." - Since all capacitors in a parallel configuration are connected directly across the same voltage source, this statement is **correct**. 3. **Analyzing Statement (II):** - **Statement (II):** "For each capacitor, charge is different." - The charge on each capacitor can be calculated using the formula \( Q = C \times V \), where \( C \) is the capacitance and \( V \) is the voltage. Since the voltage \( V \) is the same for all capacitors but the capacitances \( C_1, C_2, C_3 \) can be different, the charges \( Q_1, Q_2, Q_3 \) will also be different. Thus, this statement is **correct**. 4. **Analyzing Statement (III):** - **Statement (III):** "Voltage applied is different for each capacitor." - This statement is **incorrect** because, in a parallel configuration, the voltage across each capacitor is the same, as established in Statement (I). 5. **Analyzing Statement (IV):** - **Statement (IV):** "For each capacitor, charges are same." - This statement is also **incorrect** because, as mentioned earlier, the charges on each capacitor depend on their capacitance and the common voltage. If the capacitances are different, the charges will also be different. ### Conclusion From the analysis: - **Correct Statements:** (I) and (II) - **Incorrect Statements:** (III) and (IV) Thus, the correct answer is that statements (I) and (II) are true.
