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.
