INDUCTANCE CAPACITANCE AND RESONANCE - Practice Mode

1) How the value of capacitance can be decreased?

Increasing the plate area Increasing the resistance of the plates Increasing the distance between the plates Using high dielectric constant material

Correct Answer: Increasing the distance between the plates

2) What is the effective capacitance for three capacitors connected in parallel?

C1 + C2 + C3 C1 + C2 1/C1 + 1/C2 + 1/C3 1/C1 + 1/C2

Correct Answer: C1 + C2 + C3

3) What is the similar term in magnetic circuit for ?conductance? in electrical circuit?

Reluctivity Permeance Reluctance Permeability

Correct Answer: Permeance

4) Which is the cause for changing the permeability?

Length Flux density Field intensity Magneto motive force

Correct Answer: Flux density

Explanation:

The sound frequency range refers to the range of frequencies that can be detected and perceived by the human ear. Sound is a mechanical wave that propagates through a medium such as air or water, and it can be characterized by its frequency and amplitude.

The range of frequencies that can be perceived by the human ear is typically between 20 Hz and 20,000 Hz(20 Khz).

5) How the resonance frequency (f_r) can be increased in AC series circuit?

Reducing the inductance value Reducing the capacitance value Increasing the capacitance value Increasing the value of resistance

Correct Answer: Reducing the capacitance value
