The primary of a particular transformer has 25 turns in its coil and a voltage of 60 v. if the secondary coil has 41 turns, what is the voltage in the secondary? is this a step-up or step-down transformer?

100 volts. A step- up transformer

Explanation:

Hi, The applicable relationship is T1/T2 = V1/V2, meaning the ratio of primary voltage to secondary voltage is equal to the ratio of primary turns to secondary turns.

In this case  

T1= 25 turns

V1= 60 volts

V2=?

T2=41 turns

v2. 0,60 = 60

v2            = 60 ÷ 0,60

v2            = 100 v

This is a step up transformer, because is transformer in which the output (secondary) voltage is greater than its input (primary) voltage.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
