First explain step procedure $8$ and the that i get it $,$ the cuurent If$($red$)=10\mathrm{.}5$mA and vf$($red$)=1\mathrm{.}9*10^-3$ and the tesult of Pi$($red$)=0\mathrm{.}0115$mw explain and analyse the reult and why the pi$($red$)$ is true and i want to wtite only the equation write the what i want $.$

Also explain step procrdure $10$ and the result i get it the cuurent of If$($green$)=6\mathrm{.}67$mA and Vf$($green$)=1\mathrm{.}2$ and the pi$($green$)=8\mathrm{.}004*10^-3$ so explain again and analyise the result and why the result is true.

Also i want step procesure $12,$ the rrsult of If$($infrared$)=11\mathrm{.}77$mA and the vf$($infrared$)=2\mathrm{.}12$vdc and the pi$($infrared$)=0\mathrm{.}024$mw again explain and analyze the rrsult and why the result is true
