For the circuit shown in the figure    
  • a)
    the current I through the battery is 7.5 mA
  • b)
    the potential difference across RL is 18 V
  • c)
    ratio of powers dissipated in R1 and R2 is 3
  • d)
    if R1 and R2 are interchanged, magnitude of the power dissipated in RL will decrease by a factor of 9
Correct answer is option 'A,D'. Can you explain this answer?
Verified Answer
For the circuit shown in the figure a)the current I through the batte...
⇒ option (a) is correct.
The potential difference accros RL= potential difference accros Rp
option (b) is incorrect.

option (c) is incorrect.
The magnitude of power dissipated accross R2 is
Now when R1 and R2 are interchanged the equivalent resistance between R1 and RL
∴ Potential drop across this equivalent resistance
∴ Potential difference accros 
∴ The magnitude of the power dissipation in RL will decrease by a factor 9 if R1 and R2 are interchanged. (d) is the correct option.
