Question

Two circular rings of identical radii and resistance of 36Weach are placed in such a way that they cross each other’s centre C1 and C2 as shown in figure. Conducting joints are made at intersection points A and B of the rings. An ideal cell of emf 20 volts is connected across AB. The power delivered by cell is

  1. 80 watt    
  2. 100 watt    
  3. 120 watt    
  4. 200 watt    

The correct answer is: 100 watt


    From the figure
