Question

how much voltage is in the primary coil if there are 3200 winding in the secondary coil 500 winding in the primary and 25v in the secondary?

Answer 1

Voltage in the primary winding of the coil is 3.9 V

Step-by-step explanation:

As we know by the principle of transformer we have

`(V_s)/(V_p) = (N_s)/(N_p)`

here we know that

`V_s = 25 volts`

`N_s = 3200`

`N_p = 500`

now we have

`(25)/(V_p) = (3200)/(500)`

`V_p = 3.9 Volts`
