### Transcript

• 1. ELEC 101 Lab 6 Drawing Circuits
• 2. Lab 6 Objectives &#x2022;&#x202F; Identify Circuit connections and configuration &#x2013;&#x202F; Series Connections &#x2013;&#x202F; Parallel Connections &#x2013;&#x202F; The Series Circuit &#x2013;&#x202F; The Parallel Circuit &#x2013;&#x202F; The Series-Parallel Circuit &#x2022;&#x202F; Drawing Circuits &#x2013;&#x202F; Entering Components &#x2013;&#x202F; Rotating components &#x2013;&#x202F; Changing component values and labels &#x2013;&#x202F; Selecting and moving components or groups of components February 2004 ELEC 101 - Lab 6
• 3. Lab 6 Circuit Configurations
• 4. The Series Circuit &#x2022;&#x202F; Single path from + terminal of source, through components, to &#x2013; terminal of the source &#x2013;&#x202F; Current is the same everywhere in the circuit &#x2022;&#x202F; There are 3 nodes in the circuit shown &#x2022;&#x202F; If a component is added in series &#x2013;&#x202F; Break the circuit where you wish to add the component &#x2013;&#x202F; Enter the component and wires as necessary to complete the circuit &#x2013;&#x202F; Each component added in series adds one more node February 2004 ELEC 101 - Lab 6
• 5. The Parallel Circuit &#x2022;&#x202F; Multiple paths from + terminal of source, through components, to &#x2013; terminal of the source &#x2013;&#x202F; Current in each branch depends on value of branch resistance &#x2022;&#x202F; There are 2 nodes in the circuit shown &#x2022;&#x202F; If a component is added in parallel &#x2013;&#x202F; Enter the component in parallel where desired &#x2013;&#x202F; Add wires as necessary to complete the circuit &#x2013;&#x202F; When a component is added in parallel does not create a new node February 2004 ELEC 101 - Lab 6
• 6. The Series-Parallel Circuit &#x2022;&#x202F; R1 and R3 are in series &#x2022;&#x202F; The series combination of R1 and R3 is in Parallel with R2 February 2004 ELEC 101 - Lab 6
• 7. The Series-Parallel Circuit &#x2022;&#x202F; R2 and R3 are in Parallel &#x2022;&#x202F; The Parallel combination of R2 and R3 is in series with R1 February 2004 ELEC 101 - Lab 6
• 8. Lab 6A Components Used in this Lab
• 9. VDC- The DC Voltage Source Insert Anode, the + terminal up. Usually, the &#x2013; terminal will be grounded February 2004 ELEC 101 - Lab 6
• 10. VDC &#x2013; Battery or DC Voltage Source &#x2022;&#x202F; Orientation is significant &#x2022;&#x202F; Two Terminals &#x2013;&#x202F; Anode &#x2013;&#x202F; Cathode &#x2022;&#x202F; Enter component according to instructions or polarity of output will be reversed and considered incorrect &#x2022;&#x202F; You can change the Part Reference (VS above) and the Part Value (12VDC) &#x2022;&#x202F; DCL on the Reference or value and change in dialog box &#x2022;&#x202F; CL on Component and CR to open Property Editor February 2004 ELEC 101 - Lab 6
• 11. Property Editor &#x2022;&#x202F; The Property Editor presents the part information in a spreadsheet format &#x2022;&#x202F; All values and part information about the selected part can be edited and displayed or hidden &#x2022;&#x202F; More difficult than previous method to change values and part references since you must find the right boxes and replace the current values &#x2013;&#x202F; the red arrows in the graphic above show where to change the component value and part reference for the VDC source &#x2022;&#x202F; Usually requires horizontal scrolling &#x2022;&#x202F; There are easier ways to modify part values February 2004 ELEC 101 - Lab 6
• 12. R - The Resistor Orientation of resistors are not important &#x2013; They are linear and bilateral February 2004 ELEC 101 - Lab 6
• 13. GND/CAPSYM - Ground Make sure you change the name is 0 or PSpice will generate an error message when a simulation is attempted February 2004 ELEC 101 - Lab 6
• 14. Lab 6A Drawing a Series Circuit
• 15. Creating Schematics &#x2022;&#x202F; When drawing a schematic, it is most efficient if you &#x2013;&#x202F; Place Components &#x2013;&#x202F; Modify part values and part references if necessary &#x2013;&#x202F; Move the part references and part values if desired &#x2013;&#x202F; Move and realign components as necessary to create a professional schematic &#x2013;&#x202F; Add wires &#x2013;&#x202F; Add at least 1 ground named 0 &#x2013;&#x202F; Add one or more net alias if desired February 2004 ELEC 101 - Lab 6
