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

Answer:

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

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.

$\frac{V_{s} }{V_{p} }$ = $\frac{N_{s} }{N_{p} }$

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

$\frac{V_{s} }{200}$ = $\frac{20}{500}$

$V_{s}$ = $\frac{4000}{500}$

    = 8

$V_{s}$ = 8V

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