Question

A multipurpose transformer has a secondary coil with several points at which a voltage can be extracted, giving outputs of 6.00, 13.5, and 22 V. The input voltage is 110 V to a primary coil of 250 turns. What are the numbers of turns in the parts of the secondary used to produce the output voltages?
Ns (for 6.00 V) =  
Ns (for 13.5 V) =  
Ns (for 22.0 V) =

If the maximum input current is 2.20 A, what are the maximum output currents (each used alone)?
(in A) Is (for 6.00 V) =  
(in A) Is (for 13.5 V) =  
(in A) Is (for 22.0 V) =  

Explanation / Answer

Ns = (250/110)Vs

Ns (for 6.00 V) = 14
Ns (for 13.5 V) = 31
Ns (for 22.0 V) = 50

Is = (250*2.2)/Ns

Is (for 6.00 V) = 39.3A

Is (for 13.5 V) = 17.7A

Is (for 22.0 V) = 11A
