Inductors and Inductance

What is the function of an inductor in an electronic circuit?

• To control the resistance

• To decrease the electric spikes

• To store energy in its plates

• To oppose the generation of electric energy

What is the main difference between an inductor and a capacitor?

• An inductor stores magnetic energy, while a capacitor stores energy as electrical energy

• An inductor stores energy as electrical energy, while a capacitor stores energy as magnetic energy

• An inductor has high permeability, while a capacitor has low permeability

• An inductor has low inductance, while a capacitor has high inductance

Which type of inductor is used when the amount of inductance required is low?

• Iron Core Inductor

• Air Core Inductor

• Ferrite Core Inductor

• Iron Powder Inductor

What happens to the effective inductance when inductors are connected in parallel?

• It becomes zero

• It decreases

• It increases

• It remains the same

What is the total inductance when inductors are connected in series?

• L_Total = L₁ + L₂ + L₃

• 1/L_Total = 1 / L₁ + 1 / L₂ + 1 / L₃

• L_Total = ½ LI²

• L_Total = L₁ x L₂ x L₃

What is the energy stored in an inductor given by the equation W = ½ LI²?
