in a transformer the number of rurns in ...

in a transformer the number of rurns in the primary and secondary coils are `1000` and `3000` respectively If the primary is connected across `80V` `AC` the potential difference across each turn of the secondary will be .

A

`240V`

B

`0.24V`

C

`0.8V`

D

`0.08V`

Text Solution

Verified by Experts

The correct Answer is:
D
`V_(s)/(V_(p)) = N_(s)/N_(p)`
`V_s = N_s/N_(p) V_(p) = (3000)/(1000)xx80 = 240 V`
p.d across each turn ` = (240)/(3000) = 0.08V` .
