The correct Answer is:
To analyze the given statements, let's break down the problem step by step. ### Step 1: Understanding Statement 1 **Statement 1:** "When the plates of a charged capacitor are connected to a resistor, a current starts flowing in the resistor." - A capacitor stores electrical energy in the form of an electric field between its plates. When the plates of a charged capacitor are connected to a resistor, the potential difference (voltage) across the capacitor causes a current to flow through the resistor. - The current (I) can be described by Ohm's Law, where \( I = \frac{V}{R} \), with \( V \) being the voltage across the capacitor and \( R \) being the resistance. - Since the capacitor has a stored charge, it will discharge through the resistor, leading to a current flow. **Conclusion for Statement 1:** True ### Step 2: Understanding Statement 2 **Statement 2:** "A charged capacitor acts as a battery of steady emf." - A battery provides a constant voltage (emf) over time. However, when a capacitor discharges through a resistor, the voltage across the capacitor decreases over time as it loses charge. - The relationship between the charge (Q), capacitance (C), and voltage (V) is given by \( V = \frac{Q}{C} \). As the charge decreases, the voltage also decreases, which means the emf is not steady. - The current flowing through the resistor also decreases over time as the capacitor discharges, which further indicates that the capacitor does not behave like a battery with a constant emf. **Conclusion for Statement 2:** False ### Final Conclusion - **Statement 1 is True.** - **Statement 2 is False.** - Therefore, the correct option is that Statement 1 is true and Statement 2 is false.
