Unformatted text preview: 1/21/12 Circuit Simulator Applet Directions 1/10 Click here to go to the applet. This java applet is an electronic circuit simulator. When the applet starts up you will see a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. The moving yellow dots indicate current. To turn a switch on or off, just click on it. If you move the mouse over any component of the circuit, you will see a short description of that component and its current state in the lower right corner of the window. To modify a component (say, to change the resistance of one of the resistors), move the mouse over it, click the right mouse button (or control-click, if you have a Mac) and select “Edit”. There are three graphs at the bottom of the window; these act like oscilloscopes, each one showing the voltage and current across a particular component. Voltage is shown in green, and current is shown in yellow. The current may not be visible if the voltage graph is on top of it. The peak value of the voltage in the scope window is also shown. Move the mouse over one of the scope views, and the component it is graphing will be highlighted. To modify or remove a scope, click the right mouse button over it. To view a component in the scope, click the right mouse button over the component and select “View in Scope”. If the simulation is moving too slowly or too quickly, you can adjust the speed with the “Simulation Speed” slider. To add a new component to the circuit, click the right mouse button on an unused area of the window. This will bring up a menu that allows you to select what component you want. Then click where you want the first terminal of the component, and drag to where you want the other terminal. The menu items allow you to create: x wires x resistors; you can adjust the resistance after creating the resistor by clicking the right mouse button and selecting “Edit” x capacitors; you can adjust the capacitance using “Edit” x inductors, switches, transistors, etc. x voltage sources, in either 1-terminal or 2-terminal varieties. The 1-terminal versions use ground as the other terminal. By clicking the right mouse button and selecting “Edit”, you can modify the voltage and the waveform of the voltage source, changing it to DC, AC (sine wave), square wave, triangle, sawtooth, or pulse. If it¶s not a DC source, you can also change the frequency and the DC offset. x op-amps, with power supply limits of –15V and 15V assumed (not shown). The limits can be adjusted using “Edit”. x text labels, which you can modify with the “Edit” dialog x scope probes; these have no effect on the circuit, but if you select them and use the right mouse menu item “View in Scope”, you can view the voltage difference between the terminals....
