hi, i am using YENKA to diagram circuits. i dont get what it is doing when working out voltages in a basic series circuit. the picattached showsthe voltages it calculates. THE voltage it calculates do notadd upto the Totalvoltage.
in red i have listed the correct voltage drops. CAN anyone explain what YENKA is doing?
Thank you for the diagram. much clearer for me. What is the effect here of placing or taking away a voltmeter. Ithought the voltmeter was only displaying voltages but to take one away affects the voltages , please.??
In your first diagram you have removed the voltmeter but shorted out the 12k resistor.
In the second diagram you have broken the 100V line to add the voltmeter. The "voltmeter" has an infinite resistance so is the same as having no connection between the 100V and the resistors. An "ammeter" would be different - that has zero resistance.
