This is a fantastic application with complex level of interactivity for high school – secondary – students. Determine the value of given unknown resistor with help of volt meter, ammeter, rheostat, battery etc. In addition to our Ohm’s low free virtual physics lab application, this software allows user to connect the unknown resistance in series and parallel connection. Precise help and theory for doing this practical is given in the application. Finally plot the graph virtually between ampere and volt.
