Instead of one battery, you use two batteries in series for a total of 3.00 V, but still measure the time it takes for the voltage to rise from 0.00 to 0.95 V across the capacitor. How many time constants would it take for the voltage across the capacitor to go from 0.00 to 0.95 V in this case? O 2.0 O 0.25 O 0.50 O 0.38
