Question

3) Impedance is denoted by
a)l
b)z
c)R
d) none​

Answer 1

Answer:

Impedance is mathematically symbolized by the letter “Z” and is measured in the unit of ohms (Ω), in complex form. Perfect resistors possess resistance, but not reactance. ... The impedance phase angle for any component is the phase shift between the voltage across that component and current through that component.

Answer 2

Step-by-step explanation:

Z

Impedance is a complex number, with the same units as resistance, for which the SI unit is the ohm (Ω). Its symbol is usually Z, and it may be represented by writing its magnitude and phase in the polar form |Z|∠θ.
