Question

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/R1 2+ΔR2/R2 2 ?

Answer 1

Here i'm leaving an attachment for you...

For finding parallel resistance...use that equation which I've solved for yaa..

Hope u get this !

Keep asking :)
