Test: Parallel Impedance Circuits - Electrical Engineering (EE) MCQ

In an impedance parallel network the reactive component will either lead or lag the voltage by 90 degrees.

In an impedance parallel network the reactive component will either lead or lag the voltage by 90 degrees.

In an impedance parallel network the reactive component will either lead or lag the voltage by 90 degrees.

The reactive component in an impedance parallel circuit leads the voltage when the current leads the voltage.

The active component in an impedance parallel network will always be in phase with the voltage in the circuit. Hence the phase difference is 0.

The quadrature component is also known as the reactive component because the reactive component forms a quadrature with the voltage.

The quadrature component is also known as the reactive component because the reactive component forms a quadrature with the voltage.

IL is the current across the inductor and we know that the current across the inductor always lags the voltage across it. Hence IL lags V.

In the given circuit, the voltage across the inductor is the same as the source voltage as they are connected in parallel. The current in the inductor is IL hence IL=V/XL.

We know that I=IR+IL.
Substituting the values from the question, we get I=10A.
