## What is the role of resistance inductance and capacitance in transmission lines?

Transmission lines are characterized by a series resistance, inductance, and shunt capacitance per unit length. These values determine the power-carrying capacity of the transmission line and the voltage drop across it at full load. The resistively increases linearly with temperature over normal range of temperatures.

## How can the inductance and capacitance of transmission lines be calculated?

The inductance and capacitance per unit conductor length of multi-conductor transmission lines are related to each other. A matrix of a transmission line capacitance is obtained from the FEA model and its inverse matrix is then used to calculate the inductance of the line.

What are three factors that affect the capacitance of a capacitor?

There are three factors which influence capacitance: the size of the conductors, the size of the gap between them, and the material between them (the dielectric).

What are the factors affecting the resistance?

There are four factors affecting resistance which are Temperature, Length of wire, Area of the cross-section of the wire, and nature of the material.

### What are the factors that affect capacitance?

There are three factors which influence capacitance: the size of the conductors, the size of the gap between them, and the material between them (the dielectric). The bigger the conductors, the bigger the capacitance. The smaller the gap, the bigger the capacitance.

### What is resistance on what factors does the resistance of a conductor depend?

The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is.

How are resistance and capacitance parameters connected in long transmission lines?

Explanation: The resistance and inductance parameters are series elements of long transmission line. Capacitive susceptance and conductance parameters are shunt elements of transmission lines. It is the square root of ratio of line impedance(Z) and shunt admittance (Y). Its value varies between 40 Ω and 60 Ω.

## What are the factors affecting the resistance of a conductor?

Temperature is another factor that influences the resistance of conductor. The resistance varies linearly with temperature. The manufacturers specify the resistance of the conductor and one should use the manufacturers data. For medium and long distance lines the line inductance (reactance) is more dominant than resistance.

## What is the reactance of an inductor and capacitor?

Inductance, capacitance and resistance Inductance, capacitance and resistance • As previously discussed inductors and capacitors create loads on a circuit. • This is called reactance. • It varies depending on current and frequency. • At no frequency, or DC there is no reactance.

What is the formula for capacitance reactance and resistance?

Inductance, capacitance and resistance • Since capacitive reactance varies with frequency and capacitance the formula for this is X c =1/(2πfC) where f is frequency and C is Farads and X c is in Ohms. • Ohms law for capacitance is inverted from that used to combine resistances in series and parallel circuits.

How do you calculate inductance and capacitance in a circuit?

Inductance, capacitance and resistance • Since both reactance’s cause current to lead or lag by 90° they must be added to resistances using the Pythagorean theorem. • C2 = A2 + B2 • Z t 2 = R2 + X (c-l or l-c) 2 • Z t = the circuits total opposition to current flow. • If the circuit has no AC, or inductors and capacitors then Z t = R t
