The internal resistance of an ideal voltage source has the value equal with

Infinite

Any value

The source value

Zero

In the R, L, C parallel circuit we know R = 5[Ω], L = 10[mH] and C = 1[μF]. The resonance frequency, fr, of the circuit will be:

Fr = 1592 [Hz]

Fr = 15 [kHz]

Fr = 150 [Hz]

Fr = 628 [mHz]

In using the analogy between the electrostatic field and the electro-kinetic field which of the analogies is incorrect:

To calculate the electric resistance using the direct method we use the relation:

The resistance of the spherical capacitor (the capacitor plates are two metallic spheres, concentric, of external radius a and internal radius b, and the dielectric between the spheres has the constant permitivitty ε and constant resistivity ϝ), is:

R = ϝ / (4π ) * (a-b) / (r_i*r_e), [Ω]

R = ϝ / (4π ) * (a-b) / (a*b), [Ω]

R = ϝε / (4π ) * (a-b) / (a*b), [Ω]

R = ϝ / (4π ) * (r_e-r_i) / (r_i*r_e), [Ω]
