The turns ratio N2/N1 equals the factor by which the voltage increases: V2/V1.
V2/R is the secondary current
V2*I2 is the secondary power, and it equals the primary power.
An ideal transformer has 50 turns in its primary coil and 250 turns in its secondary coil. 12 V is connected to the primary.
a)find the voltage across the secondary coil.
b) find the current in a 10-ohms device connected to the secondary.
c) find the power supplied to the primary.

secondary coil 60v
vs=VP*ns
50vs=250*12
50vs=3000รท50
vs=60v
50vs=250*12
50vs=3000รท50
vs=60v
