Detailed Solution for Test: Parallel Impedance Circuits - Question 2

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

Test: Parallel Impedance Circuits - Question 3

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

Detailed Solution for Test: Parallel Impedance Circuits - Question 3

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

Test: Parallel Impedance Circuits - Question 4

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

Detailed Solution for Test: Parallel Impedance Circuits - Question 4

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

Test: Parallel Impedance Circuits - Question 5

 The phase difference between the active component of an impedance parallel circuit and the voltage in the network is __________

Detailed Solution for Test: Parallel Impedance Circuits - Question 5

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.

Test: Parallel Impedance Circuits - Question 6

The quadrature component is also known as?

Detailed Solution for Test: Parallel Impedance Circuits - Question 6

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

Test: Parallel Impedance Circuits - Question 7

The quadrature component is also known as?

Detailed Solution for Test: Parallel Impedance Circuits - Question 7

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

Test: Parallel Impedance Circuits - Question 8

 What is the phase relation between IL and V from the following circuit?

Detailed Solution for Test: Parallel Impedance Circuits - Question 8

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.

Test: Parallel Impedance Circuits - Question 9

 What is the expression for the current in the inductor from the following circuit?

Detailed Solution for Test: Parallel Impedance Circuits - Question 9

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.

Test: Parallel Impedance Circuits - Question 10

Find the total current if IL=2A and Ir=8A.​

Detailed Solution for Test: Parallel Impedance Circuits - Question 10

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