Atransformer has 1300 turns in the primary coil and 140 turns in the secondary coil. part a if the primary coil is connected to a 120 v outlet and draws 0.050 a , what are the voltage and current of the secondary? if the primary coil is connected to a 120 outlet and draws 0.050 , what are the voltage and current of the secondary? 1100 v , 5.4×10−3 a 1100 v , 0.46 a 13 v , 5.4×10−3 a 13 v , 0.46 a

correct answer is option d) 13 V and 0.46 A

Explanation:

given,

primary coil,

Number of turns N₁ = 1300

Voltage of the primary coil V₁ = 120 V

Current in the primary coil, I₁ =0.05 A

secondary coil,

Number of turns coil N₂ = 140

voltage calculation,

V₂ = 13 V

current calculation:

I₂ = 0.46 A

hence, correct answer is option d) 13 V and 0.46 A
