4. A video game console requires 6 V to operate correctly. A transformer allows the device to be powered from a 120-V outlet. If the primary has 500 turns, how many turns for the secondary?
According to the given problem,
The Transformer has,
no. of primary turns, N1 = 500
no. of secodary turns, N2 = ? (to be calculated)
primary voltage, V1 = 120V
secodary voltage, V2 = 6V
Using the formula,
Transformer ratio, ( N1 / N2 ) = ( V1 / V2 )
therefore, N2 = ( V2 / V1 ). N1 ------------------------------- (1)
substituting values in eqn. (1), N2 = ( 6 /120 ) X 500
N2 = 25 turns
Secondary of transformer has, 25 turns.
