Power in a Parallel CircuitPower computations in a parallel circuit are basically the very same as those used for the series circuit. Since power dissipation in resistors is composed of a heat loss, power dissipations are additive nevertheless of just how the resistors are associated in the circuit. The complete power is same to the amount of the strength dissipated by the separation, personal, instance resistors. Favor the collection circuit, the full power spend by the parallel circuit is:

*
Example. Discover the full power consumed by the circuit in figure 3-48.Figure 3-48. - example parallel circuit.

Given:
*

Solution:

*

Since the total current and source voltage are known, the total power can likewise be computed by:Given:
*
Solution:
