To increase complex impedance percentually, you can either increase the resistive (real) component, the reactive (imaginary) component, or both. For example, increasing the resistance in a circuit will enhance the overall impedance proportionally. Additionally, adjusting capacitive or inductive components can shift the reactive part, affecting the total impedance's magnitude. The percentage increase can be calculated by comparing the new impedance to the original impedance value.
What else can I help you with?
If impedance of power transformer is increase from 8 to 10 percentage then what will effect?
if the designed value of percentage impedance is change, for general this should affect tow things * if the percentage impedance is decrease this should increase the fualt level current *if the percentage impedance is increase this should increase the transformer losses and tempreture rise so the designed value of percentage impedance is determined according IEC if it is less than or equal 10% the margin should be + or_ 15%, if it is more than 10% the margin should be + or _ 15% so the percentage impedance of this transformer is not accepted according IEC standers
What was the effect on the input impedance of lowering the operating frequency?
The input impedance should increase slightly for the lower frequency, when using a capacitive circuit.
What is normalization of the impedance?
Normalization of impedance refers to the process of expressing the impedance of a circuit or component relative to a standard reference value, typically the characteristic impedance of a transmission line or system, such as 50 ohms or 75 ohms. This technique simplifies the analysis and design of RF and microwave circuits by allowing engineers to visualize and compare impedances on a normalized scale, often using a complex plane (like the Smith chart). Normalized impedance is calculated by dividing the actual impedance by the reference impedance, resulting in a dimensionless value that facilitates easier calculations and understanding of impedance matching.
To increase the range of a dc ammeter you would use a?
To increase the range of an ammeter, you connect a very low impedance resistor in parallel with the ammeter.
Give the equation for determining the total impedance in a inductive and resistive circuit?
Simple addition, but it must be done with complex numbers.
State the application of RC coupled amplifier?
To increase the power gain ,high input impedance,low output impedance,and increase the weaken signal

What is the impedence?
Impedance is the complex form of resistance. Impedance takes into account capacitance and inductance in a circuit as well. Impedance can be represented as resistance as a function of frequency.See link.AnswerImpedance is not a 'complex form of resistance'. It is the vector sum of a circuit's resistance and reactance. In electrical engineering, 'resistance' has a very specific meaning, and cannot be used to denote 'opposition'.
What was the effect on the input impedance of lowering the operating frequency?
The input impedance should increase slightly for the lower frequency, when using a capacitive circuit.
Why is energy lost in power transmission lines?
Increase the voltage in the lines.
What is the unit of a impidance?
Impedance is expressed in units of 'ohms'.In a DC situation, impedance is simply the scalar resistance.In a circuit where voltage/current have time-varying components,impedance is a complex quantity, with both magnitude and angle.
What is bootstraping in darlington emitter follower?
Connecting a resistance btw the o/p and i/p of the amplifier to increase the i/p impedance is called bootstrapping..
Why is impedance represented by the letter z in electronics?
I would hazard that the letter Z was chosen for because it's the last letter of the Roman alphabet. The connection is that Omega is the last letter of the Greek alphabet and is the unit symbol used for impedance. Either that or its on heck of a coincidence!

What is the effect of transformer impedance on short circuit current?
Short circuit current will increase a lot.
What is surge impedance in power systems?
Actually surge impedance is present in a transmission line due to the capacitance of transmission line. Now this capacitor attends the reactive power of the transmission line to energise its magnetic flux. now due to the flux the impedance will increase and the power is reactive too. due to the impedance loss is more.

To increase the range of an ammeter, you connect a very low impedance resistor in parallel with the ammeter.
