What is reactance formula?

Reactance formula The total reactance (X) is equal to the difference between the two: Total Reactance, X =XL – Xc. a. Capacitive Reactance Xc. The reactance, which is large at low frequencies and small at high frequencies is known as capacitive reactance (Xc).

What are the units of inductive reactance?

Inductive reactance is expressed in ohms. (The unit of frequency is hertz, and that of inductance is henry.)

What is the unit of admittance?

siemens
The SI unit of admittance is the siemens (symbol S); the older, synonymous unit is mho, and its symbol is ℧ (an upside-down uppercase omega Ω). Oliver Heaviside coined the term admittance in December 1887.

What is impedance unit?

The unit of impedance, like that of resistance, is the ohm. The reciprocal of the impedance, 1/Z, is called the admittance and is expressed in terms of the unit of conductance, the mho unit (ohm spelled backward).

What is the SI unit of capacitive reactance?

ohms
The S.I unit of capacitance is farad, but the S.I unit of capacitive reactance is ohms.

What is the unit of impedance?

ohm
The unit of impedance, like that of resistance, is the ohm.

What is the unit of admittance co2?

Explanation: The unit for admittance is ohm-1 because the unit of impedance is ohm and admittance is the reciprocal of impedance.

Which unit is used to measure reactance and impedance?

Reactance is mathematically symbolized by the letter “X” and is measured in the unit of ohms (Ω).

What is reactance in electrical engineering?

Reactance (also known as electrical reactance) is defined as the opposition to the flow of current from a circuit element due to its inductance and capacitance. Greater reactance leads to smaller currents for the same applied voltage. The reactance is inductive if it releases energy in the form of a magnetic field.
