A Simple Example
| A Simple Example:to measure the voltage of a battery directly with a voltmeter Let's make a simple example experiment together. In this experiment, we are going to measure the voltage between the two ends of a battery cell with a voltmeter. a) Run Jhksoft Electricity Lab. b) Click "New" button in the Tool Bar to create a new experiment. c) Click Battery of Power Supply Category in the Components Box with the mouse and then click at a chosen place in the Experiment Zone to lay the Battery inside the Experiment Zone. d) By the method, lay a pointer voltmeter inside the Experiment Zone. e) Next, we are going to connect these two components with linking wire. There are corresponding terminals on each component for the connection of wires. In Jhksoft Electricity Lab the symbol "+" is used to indicate a terminal for connection. The correct method to connect a wire: click with the mouse at one terminal "+", move the cursor away and click again at the other terminal "+". By so doing the two terminals will be connected with a wire. While connecting terminals with wires, a wire always can make a turn if clicked at any free space inside the Experiment Zone. After connection of a wire, the turning point can be dragged with the mouse. f) Just like the situation in a real experiment, as soon as the completion of the wiring, the voltage between the two ends of the battery is clearly indicated. g) Jhksoft Electricity Lab also provides the function for reminding when a wire is wrongly connected. For example, if you happen to connect the two ends directly with a wire, the battery will surely be short-circuited. In such a case, the software will identify the mistake automatically and pop up an alarm. To delete a wire, right click the wire with your mouse, choose "Delete" in the pop-up menu and click it. B y this simple example, we are sure that you have already a brief understanding of Jhksoft Electricity Lab. If you want to make more electricity experiments, please have a look at the various components for experiments provided by the system. Next: C omponents in Electricity Lab |
