Extracted text: FN.Q5 – A Transformer has primary windings as Np = 720 and secondary windings as Ns = 144. Its secondary voltage is Vs = 42V and output power of the transformer is PN= 2750W. The value of loses powers are Pcu = 52,5W and Pre = 39W. The resistance of loads are RLI = 1,660 and R12 = 1,950. (Pcu and PFE will be considered to be approximately the same in different load values.) Determine the following values in the circuit: Primary winding Secondary winding N, turns Ng turns Magnetic Flux, Primary current ISL Secondary 4 current Primary voltage ISL1 (ISL2 Secondary voltage RL1 R12 Transformer Core (a) the primary voltage VP, (b) the secondary load current Isı, if the transformer is rated at RLI and R12, (c) the primary load current IpL, (d) the load resistance R13 when the transformer is fully loaded by third in parallel, (e) efficiency n (fully loaded)
