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

Triss [41]

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.

What is the speed of light in (a) crown glass n= 1.52, (b) Lucite n = 1.51, and (c) ethyl alcohol n = 1.36?

mote1985 [20]

Answer:

$(a)\\1.97\times 10^8 m/s\\(b)\\1.99\times 10^8 m/s \\(c)\\2.21 \times 10^8 m/s$

Explanation:

According to the definition of refractive index, the refractive index of the material is defined as the ratio of speed of light in vacuum to the speed of light in medium.

(a) refractive index, n = 1.52

$n=\frac {c}{v}\\\\1.52 = \frac{3\times 10^8}{v}\\\\v = 1.97\times 10^8 m/s$
