To calculate the equivalent parallel impedance:
\[ I = \frac{1}{ \left(\frac{1}{i_1} + \frac{1}{i_2} + \frac{1}{i_3} + \cdots + \frac{1}{i_n} \right)} \]
Where:
Parallel impedance refers to the equivalent impedance of a circuit where multiple components are connected in parallel. In a parallel circuit, each component shares the same voltage across it. The equivalent impedance is calculated to determine the overall resistance of the parallel components. This calculation is essential in electrical engineering to understand how different components affect the total impedance of a circuit.
Let's assume the following impedances:
Using the formula:
\[ I = \frac{1}{ \left(\frac{1}{10} + \frac{1}{20} + \frac{1}{30} \right)} = \frac{1}{0.1 + 0.05 + 0.0333} \approx 6.67 \text{ Ω} \]
The equivalent parallel impedance is approximately 6.67 Ω.
