if you answer I'll mark you brainliest ​

Answer 1

Answer with explanations:

V=I1*R1=I2*R2 (when R1 and R2 are connected in parallel)

Therefore, rearranging above, I1/I2=R2/R1

Heat produced = I^2R

Ratio of heat produced by R1 and R2

= (I1^2*R1) / (I2^2*R2 )

= (I1/I2)^2 * (R1/R2)

= (R2/R1)^2 * (R1/R2)

= R2/R1
