This video will demonstrate basic operating point analysis in Circuit Lab. After your circuit is complete, click on the simulate tab and then the run DC Solver button. To get the value of any component, merely click on the component when the pen appears in conjunction with a small ball. To get the values of a resistor or other component that is not connected to ground, you must click on both ends of it and then use the Add Expression tool to subtract the difference between the further end from the closer end. This will give you the net voltage across the component. If you are measuring one that is connected to ground, merely clicking on the end that is not connected to the ground directly will give you the current or envoltage across that part. If a negative voltage appears, this means that you have clicked in an opposite direction of current flowing. This pretty much concludes how basic operations in Circuit Lab are handled.
