Procedure This is a combination circuit driven by a single ac source. The impedances can be resistive and/or reactive. **Step 1**--Determine the total impedance of the circuit. This is a parallel circuit: Z_{T} = Z_{1} + Z_{2} || Z_{3} **Step 2**--Use Ohm's Law to determine the total current: I_{T} = V_{T} / Z_{T} **Step 3**--Find the current and voltage for Z_{1}: - I
_{Z1} = I_{T} - V
_{Z1} = I_{T}Z_{1} **Step 4**--Determine the current and voltage for Z_{2} - V
_{Z2} = V_{T} – V_{Z1} - I
_{Z2} = V_{Z2} / Z_{2} **Step 5**--Apply the same procedure as Step 4 to find the current and voltage for Z_{3}. - V
_{Z3} = V_{Z2} - I
_{Z3} = V_{Z3} / Z_{3} **Check the results:** V_{Z1} + V_{Z2} = V_{T} |
