(C) For the given transformer,the primary voltage is $V_P = 230 \ V$,the secondary voltage is $V_S = 23 \ V$,and the secondary resistance is $R_S = 115 \ \Omega$. First,calculate the current in the secondary coil $(I_S)$: $I_S = \frac{V_S}{R_S} = \frac{23 \ V}{115 \ \Omega} = 0.2 \ A$. In an ideal transformer,the power input equals the power output $(V_P I_P = V_S I_S)$. Therefore,the current in the primary coil $(I_P)$ is given by: $I_P = \frac{V_S I_S}{V_P} = \frac{23 \ V 	imes 0.2 \ A}{230 \ V} = 0.02 \ A$.
