What is definition of impedence?
Impedance is usually written in equations as Z. Impedance is the real resistance (usualyl referred to as R), and the imaginary / reactive opposition (using an imaginary number 'i' or 'j', depending on your area of study). Z = R + j*n, where 'n' is the reactive opposition.Additional AnswerCurrent, in an A.C. circuit, is opposed by the resistance(R) of that circuit and the reactance (X) of that circuit. Reactance may be 'inductive reactance' (XL) or 'capacitive reactance' (XC) -depending on the nature of the circuit.Inductive reactance is directly proportional to the supply frequency; capacitive reactance is inversely proportional to the supply frequency; resistance is independent of frequency.Impedance (Z) is the vector sum (not algebraic sum) of a circuit's resistance and reactance, and may be considered as the total opposition to the flow of A.C. current.Resistance, reactance, and impedance are each measured in ohms.
How much is a resistor for an electronic circuit?
Resistors are tiny devices on circuit boards. Prices should range but should not be expensive but dependent on the materials used and the nature of conductivity.
What is power factor of resistor?
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
Why electricity does not flow through an open circuit but flows through a closed circuit?
Electricity does not flow in open circuit because the path is not a complete circuit and has the maximum impedance to flow of electricity while it flows in short circuit because electricity always wants a path with least impedance to flow which short circuit is one of such pathAnswerCurrent can jndeed flow through an open circuit. A capacitor is an open circuit, yet it will allow a d.c. current to flow for a short period of time, and an a.c. current can flow continuously.
Why is heat observed when current flows through the circuit?
The heat observed in a circuit is the result of electrical resistance.Under normal circumstances, every electrical circuit has a certain amount of resistance to the flow of electricity. Electronflow opposed by the physical nature of the conductor. This is the fundamental nature of electrical resistance. Whenever this happens, the energy of those electrons is absorbed by the conductor (as opposed to flowing through) which then emitts this captured energy as heat. The higher a conductor's resistance, the more electrical energy is converted to heat by it.

What is phase diagram in series LCR circuit?
A phase diagram in a series LCR circuit shows the phase relationship between current and voltage at different frequencies. It helps in understanding the leading or lagging nature of current with respect to voltage. The diagram typically shows a phase shift between voltage and current, with the direction and magnitude of the shift depending on the circuit's impedance at a given frequency.
What is the difference between impedance and resistance?
Resistance is a concept used for DC (direct currents) whereas impedance is the AC (alternating current) equivalent. Resistance and impedance have different fundamental origins even though the calculation for their value is the same: R=V/I
Impact of voltage in a simple circuit?
I don't understand the nature of the question. Voltage makes the circuit do things....
Why resistance is neglected for fault finding?
A fault can be resistive in nature, and the amount of resistance in the fault is unpredictable. It is unusual for a fault to be inductive or capacitive, so a typical method is to determine the impedance to the fault, and compare only the inductive part of this to the inductive part of the line impedance.
Why does electricity take the path of least resistance?
Electricity takes the path of least resistance because it follows the easiest route to flow through a circuit. This is due to the nature of electrical currents, which always seek the path with the least resistance to minimize energy loss and heat generation.
Open circuit and short circuit test?
Open circuit means the circuit is not continuous . A short circuit is continuous but has a fault connecting between either live to neutral or earth .As result of this we saw that this answer is unsufficent to explain short and open circuit on the other hand you can use this answer also like i did:)
The value of resistance of an short circuit?
The value of resistance when there is a short circuit varies depending on the nature of the fault, but it could be fractionally above zero or higher.
What is a lump circuit?
A lumped circuit is a circuit where the physical dimensions of the components are small compared to the wavelength of the signals being used. It allows for simplified analysis without considering the distributed nature of the circuit. Components in a lumped circuit are represented as single points.
How much is a resistor for an electronic circuit?
Resistors are tiny devices on circuit boards. Prices should range but should not be expensive but dependent on the materials used and the nature of conductivity.
How do you control people from polluting nature?
Enforce strict environmental regulations and penalties for those who violate them. Increase awareness through education and campaigns about the importance of protecting nature. Invest in sustainable practices and technologies to minimize pollution.
What is diagonal analysis?
The process of analyzing the task and responsibilities in jobs of a support nature in the same work group but below supervision to find those that are appropriate for loading into the job in question. Diagonal loading can be considered from higher level jobs in other work groups in some situations.
