answers passed
The inductor voltage is proportional to the rate of change of the current through the inductor. -
ANS ✔True
What is a dielectric material used in constructing capacitors? - ANS ✔A dielectric material is a
material through which virtually no current flows, assuming normal operating voltages
The capacitor is made of two conductive plates separated by a dielectric layer as shown below.
If each plate is enlarged to double its area while everything else stays the same, what happens
to the original stored energy? - ANS ✔It is doubled.
The current flowing through an inductor is increasing in magnitude. Select the correct
statement regarding the inductor energy. - ANS ✔Energy is flowing into the inductor.
To what circuit element is an ideal inductor equivalent for circuits with constant currents and
voltages? - ANS ✔An ideal inductor is the equivalent of a short circuit.
To what circuit element is an ideal capacitor equivalent in circuits for which the currents and
voltages are constant with time? - ANS ✔Open circuit
The _____ cannot change instantaneously. - ANS ✔Current through an inductor
If the current through an ideal inductor is constant with time, what is the value of the voltage
across the inductor? - ANS ✔Voltage is Zero
