It can be observed from the chart that one time constant is the length of time required for current to build to

63.2 percent of its maximum value, or from its maximum value to zero.

Q. How many time constants will be required for the current in the figure below to reach its maximum value

after the switch is closed?

33.

What is the L/R time constant of the circuit shown below?
