AB is part of a circuit as shown, that absorbs energy at a rate of 50 W.E is an emf device that has no internal resistance. A. Potential difference across AB is 48 VB. Emf of the device is 48 VC. Point B is connected to the positive terminal of ED. Rate of conversion from electrical to chemical energy is 48 W in device E |

Answer» Correct Answer - B::D Resistance absorbs energy at the rate of 2W Potential difference across AB `rArr V_(AB).I=50 W` `V_(AB)=50V` Drop across resistor is 2V, therefore EMF of E is 48 V As AB is absorbing energy at the rate of 50 W, 48 W is being absorbed by E. Thus E is on charging. i.e. currunt is entering from +ve terminal of E. |
