What is impedance triangle and power triangle?

The triangle that is created when adding the resistance to the reactance is known as an impedance triangle. Figure 22. Impedance triangle. In an impedance triangle, the resistance (r) is always on the bottom of the triangle, the reactance (x) always goes on the side and the hypotenuse is always the impedance (z).

What is the relationship between impedance and voltage?

Impedance reduces to resistance in circuits carrying steady direct current. The magnitude of the impedance Z of a circuit is equal to the maximum value of the potential difference, or voltage, V (volts) across the circuit, divided by the maximum value of the current I (amperes) through the circuit, or simply Z = V/I.

What is the relationship between impedance and admittance?

When looking at admittance vs impedance, admittance is the inverse (i.e. the reciprocal) of impedance. Therefore it has the opposite function of impedance. That is, we can say it is the measure of the flow of current which is allowed by a device or a circuit.

What is the inverse of impedance?

Admittance
The inverse of impedance is called “Admittance”. Conductance, Susceptance, and Admittance are all denoted by the variables Y or G, and are given the units Siemens.

What is imaginary part of the admittance of a parallel RLC circuit?

As the admittance, Y of a parallel RLC circuit is a complex quantity, the admittance corresponding to the general form of impedance Z = R + jX for series circuits will be written as Y = G – jB for parallel circuits where the real part G is the conductance and the imaginary part jB is the susceptance.

What is impedance find the impedance of a series RLC circuit?

Z=√R2+(XL−XC)2 Z = R 2 + ( X L − X C ) 2 , which is the impedance of an RLC series AC circuit. For circuits without a resistor, take R = 0; for those without an inductor, take XL = 0; and for those without a capacitor, take XC = 0.
