Question

For the circuit shown in the figure

(a) the current I through the battery is 7.5 mA 

(b) the potential difference across R_L 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 R_L will decrease by a factor of 9

Answer 1

Correct option: (a, d)

Explanation: 

For potential difference across R₂
