The rms current, in amperes, in the secondary winding is 0.5 A and the rms current, in milliamperes, in the primary winding is 31.25 mA.
The rms current, in amperes, in the secondary winding is calculated as follows;
V = IR
I = V/R
I = 7.5 / 15
I = 0.5 A
The rms current, in milliamperes, in the primary winding is calculated as follows;
[tex]\frac{I_p}{I_s} = \frac{V_s}{V_p} \\\\I_p = \frac{V_sI_s}{V_p}\\\\I_p = \frac{7.5 \times 0.5}{120} \\\\I_p = 0.03125\\\\I_p = 31.25 \ mA[/tex]
Thus, the rms current, in amperes, in the secondary winding is 0.5 A and the rms current, in milliamperes, in the primary winding is 31.25 mA.
