Question

The diagram shows a multi-tap transformer. Which pair of terminals would you connect to produce an output voltage of 8 V?​

Answer 1

The pair of terminals to produce an output voltage of 8V are K and M.

Step-by-step explanation:

A transformer is an electronic device that can be used to increase or decrease an output voltage. It consists of secondary and primary coils, and operates on the principle of induction.

`(V_(s) )/(V_(p) )` =
`(N_(s) )/(N_(p) )`

where:
`V_(s)` is the voltage in the secondary coil,
`V_(p)` is the voltage in the primary coil,
`N_(s)` is the number of turns in the secondary coil and
`N_(p)` is the number of turns in the primary coil.

In the question, let us combine the number of turns in the secondary coil. So that,

`N_(s)` = 15 + 5 = 20

`(V_(s) )/(200)` =
`(20)/(500)`

`V_(s)` =
`(4000)/(500)`

= 8

`V_(s)` = 8V

For the output voltage to be equal to 8V, the pair of terminals required are K and M.
