The current, lo (measured in amperes). decreases to amperes after t seconds according to the formula I = loe^-0.511 When 8 amperes decreases to 3.2 amperes, the equation is 3.2 = 8e^-0.51t Rounded to the nearest tenth of a second, how long, t, does it take for the current to decrease from 8 amps to 3.2 amps?
t=0.4 second
t=1.8 seconds
T= 2.5 seconds
t=0.7 second
