AB is part of a circuit as shown that absorbs energy at a rate of 50W. E is an emf device that has no internal resistance.

A

Potential difference across AB is 48 V

B

Emf of the device is 48 V

C

Point B is connected to the positive terminal of E

D

Rate of conversion from electrical to chemical energy is 48 W in device E

Text Solution

Verified by Experts

The correct Answer is:
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.
