The capacitor in the circuit shown below is initially uncharged. The switch is closed at t = 0 s. AV battery = 30 V, C = 3.0 F, and R = 2.0 2. What is the current in the circuit at t = 3.1 s, in Ampere? 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.
