Question

if R1,R2 andR3 three resistance are in series .what will be equivalent resistance​

Answer 1

Answer:

The resistances in given diagram are in parallel combination , therefore equivalent resistance of the given combination ,

     1/R=1/R1+1/R2+1/R3 ,

it is clear from the equation that value of Ris less than R1 orR2 or R3=1 , therefore equivalent resistance of this combination is less than 1 ohm .

Answer 2

Answer:

If R1,R2 and R3 are connected in series,

Then Equivalent resistance is

Req=R1+R2+R3
