Predict the polarity of the capacitor in the situation described by adjoining Fig. 6.27. Explain the reason too. |
Answer» Solution :In the situation shown in Fig. 6.27, in accordance with Lenz.s LAW, when seen from left hand side the induced current appears to be FLOWING anticlockwise in the CIRCULAR LOOP and when seen from right hand side, the induced current appears to be flowing clockwise. Thus, it is clear that plate A of capacitor will be at a higher potential than the plate B. In other words, the polarity of plate A will be positive with RESPECT to plate B in the capacitor.
