Two resistances R1(100 pm 3)Omega" and "...

Two resistances `R_1(100 pm 3)Omega" and "R_2 =(150 pm 2)Omega` are connected inseries. What is their equivalent resistance?

Text Solution

Verified by Experts

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