Assume you want the current through a 1.95 H inductor in series with a 0.25 Î resistor to be reduced to 0.100 percent of its original value.
Part (a) Determine how much time is required to do this?
Part (b) Approximate this calculation in the following way: round the time this took divided by the RL time constant to an integer. Then compute the time it took.
Part (c) Obtain by what percent are the times different?
