Question

Three identical resistors have an equivalent resistance 15.6 ohm when they are connected in series. What is the resistance for each resistor

Answer 1

`R=5.2\ \Omega`

Step-by-step explanation:

In series combination, the equivalent resistance is given by :

`R_(eq)=R_1+R_2+R_3+...`

Let the identical resistors be R. We have,
`R_(eq)=15.6\ \Omega`

So,

`R+R+R=15.6\\\\3R=15.6\\\\R=(15.6)/(3)\\\\R=5.2\ \Omega`

So, the resistance of each resistor is
`5.2\ \Omega`.
