- Using and installing the program Circuit
-
- Purpose of the Program:
- The purpose of this program is to allow the user to
- investigate different series and parallel circuits and to infer the
- relationship between the voltage, resistance, and current in the
- system. The unregistered copy will allow 3 resistors and the
- registered copy allows up to 19 resistors. The resistors can be
- connected in series, parallel, or a combination.
- Setting up circuits to illustrate ohms'law and resistors in
- series and parallel can be tedious and expensive. Usually lab
- groups are very large due to the unavailability of equipment. This
- program allows the student to create complex series, parallel, and
- combination circuits with up to 19 resistors. The relationship
- between resistance, potential difference, and current can be
- inferred by the student by trying different combinations of
- resistors. A lab which accomplishes this task is included with the
- registered copy. See register.txt for more information.
-
- Installing Circuit on your hard drive:
- To install circuit on your hard drive type start windows and
- click on File in the upper left hand corner of Program Manager.
- Choose Run from the file menu and type and enter path\install where
- path is the location of the circuit files. For example, if the
- files are on the root directory of A drive you would enter
- A:\install. Install will create a directory called C:\circuit,
- copy all of the appropriate files, and create the necessary icons.
-
-
- Using the Program:
-
- Circuit Menu
- This menu can be used to create a new circuit, open an
- existing circuit, save a circuit, save a circuit under another
- name, or exit the program.
-
- New Item
- Clicking on this item will allow the user to start a new
- circuit. A dialog box will appear asking for the voltage and the
- internal resistance of the power supply. Use the mouse or TAB key
- to move from box to box.
-
- Open Item
- When choosing this menu item a dialog box will occur
- containing all previously stored circuits. Select the desired file
- and it will appear in the main window.
-
- Save Item
- When choosing this menu item the current circuit will be saved
- to disk. If the circuit is new the user will be prompted for a
- file name. Use a file name of 8 letters (no spaces) or less.
-
- SaveAs Item
- When choosing this menu item the current circuit will be saved
- to disk under a file name different than the present file name.
- The user will be prompted for a file name. Use a filename of 8
- letters (no spaces) or less.
-
- Exit Item
- To quit the program choose this item or press Alt-x.
-
- Edit Menu
-
- This menu allows the user to Move , Undo , or Change the
- properties of a power supply or resistor.
-
- Move Item
-
- To move a power supply or resistor to another location on the
- screen click on this menu item. Click the left mouse button on the
- device to be moved and drag it to its new location. If there are
- any wires attached to the device you will not be able to move it.
-
- Click on undo until there are no wires attached to the device.
-
- Undo Menu Item
-
- To return to a previous state of the circuit click on this
- menu item or press the backspace key.
-
- Change Menu Item
-
- To change the properties of a power supply or resistor(voltage
- and internal resistance for a power supply, resistance for a
- resistor) click on this menu item. Click the left mouse button on
- the device you want to change the properties of and then enter the
- new values into the dialog box provided.
-
-
- Procedure for setting up a circuit
-
- To create a circuit click on the resistor icon on the left of
- the screen. A message box will appear telling the user to click
- the left mouse bottom at the location the resistor is to be added.
- After this is completed a dialog box will appear. Enter the
- desired resistance of the resistor. You may between 0 to 100
- ohms in the dialog box. In the registered version up to 19
- resistors can be included in a circuit. The unregistered
- version allows only 3 resistors. See register.txt for more
- information. You may add wires to the resistors on the screen at
- any time. Click on the wire icon on the left of the screen. You
- will be prompted to click the left mouse button on the terminal to
- be connected and then to drag the mouse to the other terminal to be
- connected. You may only join a positive to negative terminal for
- resistors and like polarities when joining the power supply to any
- resistors. When a circuit is complete a message box will appear.
- Clicking on Run will have the computer calculate all of the
- currents in the circuit. Resistors may be added to a completed
- circuit if they are placed in parallel to existing resistors. If
- a mistake is made when setting up a circuit click on Edit|Undo(or
- press the backspace key) until the circuit is in the state desired.
