Suppose the charge on a capacitor in a circuit is oscillating so that, Q(t) = Qmaxsin(wt), where Qmax = 2.54 μC, and w = 5.8 s-¹ = 5.8 Hz? Write a symbolic expression for the current flowing on and off the capacitor, in terms of Qmax, w, and t, then calculate its numeric value at t = 6.5 sec. 1=wQmaxcos (wt) | 11 HA

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. Cil
