Test: Oscillation of Energy at Resonance - Question 2

### The energy stored in the inductor is of _________ nature.

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 2

The energy stored in a capacitor is in the form of electrostatic energy whereas the energy stored in the inductor is in the form of magnetic energy.

Test: Oscillation of Energy at Resonance - Question 3

### At resonance, the circuit appears __________

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 3

At resonance, the circuit appears resistive because the capacitive and inductive energies are equal to each other.

Test: Oscillation of Energy at Resonance - Question 4

At resonance, the capacitive energy is ___________ inductive energy.

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 4

At resonance, the capacitive energy is equal to the inductive energy and the circuit appears to be resistive in nature.

Test: Oscillation of Energy at Resonance - Question 5

At resonance, electrostatic energy is ___________ the magnetic energy.

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 5

At resonance, the capacitive energy is equal to the inductive energy and the circuit appears to be resistive in nature. The capacitor stores electrostatic energy and the inductor stores magnetic energy hence they are equal.

Test: Oscillation of Energy at Resonance - Question 6

The maximum magnetic energy stored in an inductor at any instance is?

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 6

At any instant, the magnetic energy stored in an inductor is E=LIm2/2, where Im is the maximum current and L is the value of the inductor.

Test: Oscillation of Energy at Resonance - Question 7

The maximum electrostatic energy stored in a capacitor at any instance is?

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 7

The maximum electrostatic energy stored in a capacitor at any instance is 1/2*CVm2, where C is the capacitance value and Vm is the peak voltage.

Test: Oscillation of Energy at Resonance - Question 8

Q is the ratio of?

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 8

Q is the ratio of the reactive power to the average power. The reactive power is due to the inductance or capacitance and the average power is due to the resistance.

Test: Oscillation of Energy at Resonance - Question 9

Find the value of Q if the reactive power is 10W and the average power is 5W.

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 9

Q is the ratio of the reactive power to the average power.
Substituting the given values from the question, we get Q=2.

Test: Oscillation of Energy at Resonance - Question 10

Find the reactive power when the average power is 5W and Q=2.

Detailed Solution for Test: Oscillation of Energy at Resonance - Question 10

Q is the ratio of the reactive power to the average power.
Substituting the given values from the question, we get reactive power= 10W.
