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.
Help can be obtained at any time by clicking on the Help Menu item.
