It consists of a single loop of thin phosphorbronze strip which forms the moving system. It is called a vibrator loop. The vibrator loop is situated in the field of a permanent magnet but when high sensitivities are required...
1. Define a transformer. A transformer is a static device which change the alternating voltage form one level to another. 2. What is staggering in the construction of transformers? In transformer, the joints in the alternate...
