Test: Quality Factor - Question 1

Quality factor is also known as _________

Detailed Solution for Test: Quality Factor - Question 1

Quality factor is also known as voltage magnification because the voltage across the capacitor or inductor in resonance condition is equal to Q times the source voltage.

Test: Quality Factor - Question 2

At resonance condition, voltage across the capacitor and inductor is _________ the source voltage.

Detailed Solution for Test: Quality Factor - Question 2

In resonance condition the voltage across the capacitor and inductor is greater than the source voltage because the voltage across the capacitor or inductor in resonance condition is equal to Q times the source voltage.

Test: Quality Factor - Question 3

What is the voltage across the capacitor when the source voltage is 100V and the Q factor is 10.

Detailed Solution for Test: Quality Factor - Question 3

We know that voltage across the capacitor in resonance condition is equal to Q times the source voltage =10*100=1000V.

Test: Quality Factor - Question 4

 Find the Q factor when the voltage across the capacitor is 1000V and the source voltage is 100V.

Detailed Solution for Test: Quality Factor - Question 4

We know that voltage across the capacitor in resonance condition is equal to Q times the source voltage. Vc=QV. Substituting the values from the given question, we get Q=10.

Test: Quality Factor - Question 5

Find the source voltage when the voltage across the capacitor is 1000V and the Q factor is 10.

Detailed Solution for Test: Quality Factor - Question 5

We know that voltage across the capacitor in resonance condition is equal to Q times the source voltage. Vc=QV. Substituting the values from the given question, we get V=100V.

Test: Quality Factor - Question 6

What is the voltage across the inductor when the source voltage is 200V and the Q factor is 10.

Detailed Solution for Test: Quality Factor - Question 6

We know that voltage across the inductor in resonance condition is equal to Q times the source voltage =10*200=2000V.

Test: Quality Factor - Question 7

 Find the Q factor when the voltage across the indictor is 2000V and the source voltage is 100V.

Detailed Solution for Test: Quality Factor - Question 7

We know that voltage across the inductor in resonance condition is equal to Q times the source voltage. VL=QV. Substituting the values from the given question, we get Q=20.

Test: Quality Factor - Question 8

Find the source voltage when the voltage across the inductor is 2000V and the Q factor is 20.

Detailed Solution for Test: Quality Factor - Question 8

We know that voltage across the inductor in resonance condition is equal to Q times the source voltage. VL=QV. Substituting the values from the given question, we get V=100V.

Test: Quality Factor - Question 9

 What happens to the voltage across the capacitor when the Q factor increases?

Detailed Solution for Test: Quality Factor - Question 9

 We know that voltage across the capacitor in resonance condition is equal to Q times the source voltage. Hence as the Q factor increases, the voltage across the capacitor also increases.

Test: Quality Factor - Question 10

What happens to the voltage across the inductor when the Q factor decreases?

Detailed Solution for Test: Quality Factor - Question 10

We know that voltage across the inductor in resonance condition is equal to Q times the source voltage. Hence as the Q factor decreases, the voltage across the inductor also decreases.
