Two resistances R(1) = (100 pm 3)Omega, ...

Two resistances `R_(1) = (100 pm 3)Omega, R_(2) = (150 pm 2)Omega`, are connected in series. What is their equivalent resistance?

Text Solution

Verified by Experts

`R_(1) = 100 pm 3Omega, R_(2) = 150 pm Omega`
Equivalent resistance R = ?
Equivalent resistance R = `R_(1) + R_(2) = (100 pm 3) + (150 pm 2) = (100 + 150) pm (3+2)`
R = `(250 pm 5) Omega`
