Question

The units of admittance, conductance, and susceptance are siemens.

(a) True

(b) False

Short answer

Therefore, the correct option is (a) True

Step-by-step solution

Define the formulas of admittance, conductance, inductive and capacitive susceptance.

Write the formula of admittance

$\mathbf{Y}\mathbf{=}\frac{\mathbf{1}}{\mathbf{z}}$ ……. (1)

Here, is admittance and is impedance.

Write the formula of conductance

$\mathbf{G}\mathbf{=}\frac{\mathbf{1}}{\mathbf{R}}$ ……. (2)

Here, is conductance and is resistance.

Write the formula of inductive susceptance

${\mathit{B}}_{\mathbf{L}}\mathbf{=}\frac{\mathbf{1}}{{\mathbf{X}}_{\mathbf{L}}}$ ……. (3)

Here, is inductive susceptance and is inductive reactance.

Write the formula of capacitive susceptance

${\mathit{B}}_{\mathbf{C}}\mathbf{=}\frac{\mathbf{1}}{{\mathbf{X}}_{\mathbf{C}}}$ ……. (4)

Here, ${\mathrm{B}}_{\mathrm{C}}$is capacitive susceptance and $X_C$is capacitive reactance.

Determine the units of admittance, capacitance and susceptance.

From equation (1), the unit of impedance is$\mathrm{\Omega }$and the unit of admittance is inverse of impedance, called as mho or siemens respectively =.

From equation (2), the unit of conductance issiemens.

From equation (3) and equation (4), the unit of both inductive and capacitive susceptance issiemens.

Therefore, option (a) True is correct.
