Question

For the ideal transformer in the picture, the value of R1 is5.00 Kilohm. The primary has 100 turnswhile the secondary has 590.00. If 120volts the primary voltage, determine:
The secondary voltage, VS The secondary current, IS The primary current, IP The power to the load, PS For the ideal transformer in the picture, the value of R1 is5.00 Kilohm. The primary has 100 turnswhile the secondary has 590.00. If 120volts the primary voltage, determine:

Explanation / Answer

prinicple of transformer Vs /Vp = Ns /Np secondary voltage Vs = (590/100)120       = 708V -----------------------------------------------------------------------------------------------------    primary current is Ip = (Vp)/R1    Is / Ip = Np / Ns        Is = (100 / 590)Vp / R1        = (100 / 590)120 /5k        = 4x10^-3A        =4mA ------------------------------------------------------------------------------------------------------------ Primary current is    Ip = Vp/ R1         =120/5k         = 0.024A         =24mA ---------------------------------------------------------------------------------------------------------------- power to the load is Ps = Vs Is       = (708)(4mA)      = 2.832W
