The correct Answer is:
To solve the problem, we need to analyze the initial rate of discharge of two capacitors, \( C_1 \) and \( C_2 \), which are charged to the same potential and then discharged through similar resistors. ### Step-by-Step Solution: 1. **Understanding the Problem**: We have two capacitors \( C_1 \) and \( C_2 \) where \( C_1 > C_2 \). Both capacitors are charged to the same potential \( V_0 \) and are then allowed to discharge through identical resistors. 2. **Formula for Current During Discharge**: The current \( I \) flowing from a capacitor during discharge can be expressed as: \[ I(t) = \frac{V_0}{R} e^{-\frac{t}{RC}} \] where \( R \) is the resistance and \( C \) is the capacitance of the capacitor. 3. **Initial Rate of Discharge**: We need to find the initial rate of discharge, which corresponds to the current at \( t = 0 \). Substituting \( t = 0 \) into the equation gives: \[ I(0) = \frac{V_0}{R} e^{0} = \frac{V_0}{R} \] This means that at \( t = 0 \), the current is simply \( \frac{V_0}{R} \). 4. **Calculating for Both Capacitors**: - For capacitor \( C_1 \): \[ I_1(0) = \frac{V_0}{R} \] - For capacitor \( C_2 \): \[ I_2(0) = \frac{V_0}{R} \] 5. **Conclusion**: Since both capacitors are discharged through the same resistor and have the same initial voltage, the initial rate of discharge (current) will be the same for both capacitors: \[ I_1(0) = I_2(0) = \frac{V_0}{R} \] ### Final Answer: The initial rate of discharge for both capacitors is the same.
