**URGENT** Roberto plans to use two transformers to reduce a voltage of 120 V to 4 V. He uses a transformer that has 300 coils i
skelet666 [1.2K]

As we know that in transformers we have

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

here we know that

V_s = 4 Volts

V_p = 120 Volts

N_s = 50 coils

N_p = 300 coils

now from above equation we will have

\frac{V}{120} = \frac{50}{300}

V = 20 Volts

now we have to reduce this voltage to final voltage of V = 4 V

so again we will have

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

\frac{4}{20} = \frac{N_s}{N_p}

\frac{N_s}{N_p} = \frac{1}{5}

so we need to take such a winding whose ratio is 1:5

So it is satisfied in X

N_p = 60

N_s = 12

so answer will be

<u>B)-   X</u>

Determine the smallest thickness of the film for which reflected green light of wavelength 540 nm interfere destructively. Expre
Andre45 [30]

Answer:

Explanation:

Given

Wavelength of green light \lambda =540\ nm

For destructive interference by reflection the path difference is an integral multiple of wavelength so

t=\frac{\lambda '}{2}

where \lambda '=\frac{\lambda }{n}

n=refractive index of medium

suppose water is the medium

so

n=\frac{4}{3}

t=\frac{540\times 3}{4\times 2}

t=202.5\ nm
