Question

5)Two resistors of resistances R1=100±3 ohm and R2=200±4 ohm are connected

(a) In series, (b) in parallel.

Find the equivalent resistance of the

(a) series combination,

(b) parallel combination.

Use for

(a) the relation R=R1+R2 and for

(b) 1/R=1/R1+1/R2 and ΔR1/R12+ΔR2/R22 ?​

Answer 1

Explanation:

series combination = (100+_ 3) + (200+_4)

= (300+_7) ohm

parallel combination = (100+_3) × (200+_4) / (300+_7)
