Series Circuits - Engineering

Q1:

A series circuit consists of three resistors with values of 120 , 270 , and 330 . The total resistance is

A less than 120 

B the average of the values

C 720 

D 120 

ANS:C - 720 

R1 = 270.
R2 = 330.
R3 = 120.

Series means all the resistors will be added.
then we get 720.
270 + 330 + 120 = 720.
