Parallel ac Networks

For the representative parallel ac network of [Fig. 1], the total impedance or admittance is determined as described in the previous section, and the source current is determined by Ohm's law as follows: Since the voltage is the same across parallel elements, the current through each branch can then be found through another application of Ohm's law: Kirchhoff's current law can then be applied in the same manner as employed for dc networks. or The power to the network can be determined by where $\theta_T$ is the phase angle between E and I.
Let us now look at a few examples carried out in great detail for the first exposure. RL Parallel ac Network Configuration RC Parallel ac Network Configuration RLC Parallel ac Network Configuration
