PRACTICE EXERCISE

In each of the following exercises, select the one answer that

best completes the statement or answers the question. Indicate your

solution by circling the letter opposite the correct answer in the

subcourse booklet.

SITUATION.

Assume that a DC voltage of 15 volts is applied to a series RL

circuit. The total resistance in the circuit is equal to 1,000 ohms

and the total inductance is equal to 1 millihenry.

Exercises 1 and 2 are based on the above situation.

1.

After the steady state has been reached, the voltage across the

inductor and the total current will be equal to

a.

15 volts and 15 milliamperes (mA), respectively.

b.

15 volts and 0 mA, respectively.

c.

0 volt and 15 mA, respectively.

d.

0 volt and 0 mA, respectively.

2.

The steadystate condition of the circuit described in the

situation will be reached after

a.

0.5 microsecond.

b.

1.0 microsecond.

c.

3.5 microseconds.

d.

7.0 microseconds.

SITUATION.

Assume that a DC voltage of 10 volts is applied to a series RC

circuit. The resistance of the circuit is equal to 2,000 ohms and

the capacitance is equal to 0.005 microfarad.

Exercise 3 and 4 are based on the above situation.
