A multipurpose transformer has a secondary coil with several points at which a voltage can be extracted, giving outputs of 5.60,

12.0, and 480 V. (a) The input voltage is 140 V to a primary coil of 220 turns. What are the numbers of turns in the parts of the secondary used to produce the output voltages

Answer:

for 5.6V 9 turns, for 12.0V 19 turns, for 480V 755 turns

Explanation:

Vp/Vs= Np/Ns

Vp: Primary voltage

Vs: Secondary Voltage

Np: number of turns on primary side

Ns: number of turns on secondary side

for output 5.6V

140/5.6= 220/Ns

Ns= 8.8 or 9 Turns

for output 12.0V

140/12= 220/Ns

Ns= 18.9 or 19 turns

for output 480V

140/480= 220/Ns

Ns= 754.3 or 755 turns
