Ohm’s Law

Ohm’s Law Link Steps In this activity you will be able to (i) verify Ohm’s law (ii) understand the relation between current, voltage and resistance. Open the browser and type “olabs.edu.in” in the address bar. Click physics tab and then click “Ohm’s law and resistance” under 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. Switch on the key and note down the voltage ( V ) and curren ( I ). Find the value of resistance using the formula R = V I . Repeat the experiment for different values of voltage and current. Check whether the resistance remains constant. Find the value of Resistance/(length (in Cm)). Enter the value of resistance and resistance per unit length in the result. Verify the answer. 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 .
