Question

When two identical wires made of different materials having resistivity s, and s, and conductivities
row1, and row2, are connected in series, effective resistivity is​

Answer 1

Answer 2

Answer:

Seq=(S1+S2)/2

Explanation:

R1=S1l/A

R2=S2l/A

Req=R1+R2

Req=2Seql/A

: 2Seql/A=S1l/A +S2l/A

: 2Seql/A=l/A(S1+S2)

: 2Seq=S1+S2

: Seq=(S1+S2)/2
