- The capacitor in the circuit shown is fully charged by a 24 V battery. The switch is closed at t = 0. At sometime after the switch is closed, the voltage across the capacitor is measured to be 10 V. What is the current in the circuit at this time, in Ampere? C = 3.0 µF, and R = 2.0 02. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Cil3. Write down the equation for V for this RC circuit and describe the relationship between the variables. For example, if C remains constant and R is larger, the potential difference changes (faster/slower/stays the same). 4. Write another sentence for V vs. C if R remains constant and C is increased.The capacitor in the circuit shown below is initially uncharged. The switch is closed at t = 0 s.
