A disk drive plugged into a 120V outlet operates on a voltage of 12V . The transformer that powers the disk drive has 125 turns

Serga [27]

Answer:

(A-) Number of turns in secondary coil will be less than 125.

(B-) EXPLAIN- The voltage is to be lowered. The voltage will be reduced from 120 to 9 volts. As a result, a step down transformer will be used, indicating that the secondary coil's number of turns would be less than 125.

(C-) The number of turns on the secondary coil is 12.5

Explanation:

STEP DOWN TRANSFORMER - A step-down transformer transforms high voltage (HV) and low current from the transformer's primary side to low voltage (LV) and high current on the secondary side. A phase down transformer is the opposite of this.

In electrical networks and transmission lines, a step-down transformer can be used in a number of ways.

Step down transformer formula-

$V_s=\frac{N_s\times V_p}{N_p}$

We are given with the -

Primary voltage $V_p$ = 120V

Secondary voltage $Vs=12V$

Number of primary turns $N_p=125$

To calculate the number of turns on the secondary coil -

Since , the transformer ratio is given as -

$\frac{N_s}{N_p} =\frac{V_s}{V_p}$

So, the number of turns on the secondary coil is - $N_s=N_p\times\frac{V_p}{V_s}$

Putting , the given values -:

$125\times\frac{12}{120}$

= 12.5

Therefore , the number of turns on secondary coil is 12.5 .

• how did einstein's theory of relativity lead to the development of the big bang theory.

Sauron [17]

Einstein's theory determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.
