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 .

Hi.

zhenek [66]

Answer: Units: C, T and Variables: c, C, t, T

(a) C is the unit of charge Coulomb, (e) T is the unit of magnetic field strength Tesla.

In physics, units are written straight and variables are written in italics. Various italic symbols are used for various quantities like t for time, T for temperature, c for any constant and C for curie constant.

Explain Newton's third law in your own words.

Kazeer [188]

Newton's third law states "for every action, there is an equal and opposite reaction."

What this is pretty much saying is that for every action, there is a consequence. One force connects and triggers another.

Suppose the Sun moved twice the distance from Earth. Describe immediate and future changes to our planet. Justify your reasoning

Reptile [31]

Our year would now be 2.8 times longer, we would also be receiving only 1/4 of the energy from the sun that we currently do. This means that we’d now be out beyond the orbit of Mars and right at the edge of the asteroid belt, and things would rapidly get very cold with temperatures expected to drop by around 50 degrees Celsius on average, and that’s with our current atmospheric composition which would not be stable in the new conditions. And also, any living thing on earth would die.
