What is the time constant for this circuit? (3 points) 2. If the resistance is 33202, what is the capacitance? (3 points) 3. At t=0.0040s, how much energy is stored in the capacitor? (4 points) 4. When the voltage at the capacitor is 9.00V, what is the magnitude of the current in the circuit? (3 points) 5. If the capacitor in this circuit started as fully discharged and then was attached to this same battery/resistor combination, how long would it take for it to become 78% charged? (3 points)
