Hey there!
Two resistors (R1 & R2) are connected in parallel.
We know,
1/re = 1/r₁ + 1/r₂
Then re = r₁r₂/r₁+r₂
Putting values:
=50×100/50+100
=5000/160
=100/3 ← Ans
Now, Parallel Connection error:
= R1^2 dB +R2^2dA/ (R1+R2)^2
=50×50 (3)+100×100 (2)/150×150
=7500+20000/150×150
=11/9 ← (Ans)
Relative Error =
=(11/9)/100/3
=0.03666 ←(Ans
