Question

Judge the equivalent resistance when the following are connected in parallel: (a) 10 and 10^3 0 (b) 10, 10^2 and 10^3 0.​

Answer 1

Answer:

Since 1Ω and 106 Ω are connected in parallel 

then the equivalent resistance R will be 

R1=11+1061

R=106+1106  ~ 106106

 R=1Ω

 Equivalent resistance is 1Ω 

(b) 1Ω and 103Ω and 160Ω are in parallel

R1=11+1031+1061

R1=106106+103+1

R1=10000001001001

 R=0.999Ω 

Therefore, equivalent resistance =0.999Ω
