According to Norton's theorem, which among the following are the most possibly approved conditions?

a. Replacement of multiple V & I sources by I_sc in parallel with equivalent impedance Z_eq.
b. Replacement of multiple V & I sources by I_sc in parallel with equivalent capacitance C_eq
c. Replacement of multiple V & I sources by I_sc in series with equivalent impedance Z_eq
d. Replacement of all multiple V & I sources by I_sc in series with equivalent impedance & parallel with equivalent capacitance C_eq.

Correct Answer : a. Replacement of multiple V & I sources by I_sc in parallel with equivalent impedance Z_eq.

Explanation :

The practical implication that can be derived from Norton's theorem infers that multiple voltage and current sources in any RLC circuit can be easily simplified by making the connection configuration only in parallel combination with the resultant/ equivalent value of impedances.
