Problem 1PE

(a) What is the resistance of ten 275-Ω resistors connected in series? (b) In parallel?

Step-by-Step Solution:
Step 1 of 3

Solution  1PE

a)

The equivalent resistance in series combination is,

Rs  =  R1+  R2 + R3 +....+  Rn

=  nR

= (10)(275Ω )

=  2750Ω

b)

he equivalent resistance in parallel combination is

1/Rp  = 1 / R1 + 1 / R2  +  1 / R3  + ,,,,,+ 1 / R3n

1/Rp   =  10/ 275Ω

=  275Ω / 10

=27.5 Ω

the equivalent resistance in parallel combination is 27.5 Ω
