2. During a DC circuit analysis: a) all inductors and capacitors are replaced by open-circuits b) all inductors and capacitors are replaced by short-circuits c) inductors are made open-circuit and capacitors made short-circuit d) inductors are made short-circuit and capacitors made open-circuit.

3. A DC circuit analysis is usually performed: a) after a transient analysis b) after a pole-zero analysis c) prior to a transient or pole-zero analysis d) at the same time as performing a transient analysis.

4. The transconductance of a circuit is obtained by: a) dividing the output current by the input voltage b) dividing the input current by the output voltage c) dividing the output voltage by the input current d) dividing the output current by the output voltage.
