Electric current In this activity you will be able to (a) measure the potential difference of cells (b) measure the internal resistance of a given primary cell STEPS: • Open the browser and type “olabs.edu.in” in the address bar. Click physics tab and then click “Potentiometer-Internal Resistance of a Cell” in class section. Go to “simulator” tab to do the experiment. • Construct the electric circuit as per the connection diagram by clicking “show circuit diagram” tab.
You can connect wires between electric component by dragging the mouse between the component. • To check whether the connections are correct or not, drag the jockey and place it at the two end points of the wire. If the galvanometer shows opposite deflections, the connections are correct. (keep both keys on) Note: .
One time sign up is needed to do simulation. Then login using that username and password. . Read theory, procedure and animation to get the theory by clicking the corresponding tab.
