We, herewith, bring you a perfect app on a device known as galvanometer. Our aim is to provide you with the concept-based science with much needed clarity to understand the physics behind it. This app deals with the construction and working of a galvanometer. We will give details of the principle and would explain how a torque is experienced by the current-carrying rectangular coil placed in a uniform magnetic field. Current and voltage sensitivity of the galvanometer would also be defined and discussed in detail. The learner would supplement his knowledge on the subject with the help of a quiz provided herewith. The key terms and the main image in this app would add to his knowledge tremendously. The learner would have a chance to go through some other websites to know more about the subject. We have been using much-thought-out and user-friendly techniques to keep you excited. We, at Designmate, help you learn science better.
