In physics, experiments are done to check the validity of the existing theory. And the theory is usually expected to explain experimental results. Keeping in mind the importance of experiments, the following experiments were performed by Grade 12 science students in groups of 12 in the Physics laboratory, taking full care of social distancing and sanitization. The students performed the following experiments and recorded the observations:
1.To find out the resistivity of a given wire by plotting a graph between potential difference and current
2.To determine the resistance of given wire using meter bridge
3.To compare emf of two primary cells using a potentiometer
4.To find out resistance of galvanometer and figure of merit by half deflection method
