Is a voltage source a zero or infinite impedance?
Obviously it's not infinite impedance--that would mean it soaks up all the voltage. It can't be zero impedance either...that would be a superconductor, and there aren't many of those around. Voltage sources have impedance, but it's not infinite. Sometimes the impedance of the source is critical--radio frequency amplifiers have to be impedance matched to their transmitting antennas if you don't want to burn them out.
What is meant by apparent impedance?
You may be mixing up 'impedance' with 'apparent power'.Impedance is the vector sum of an a.c. load's resistance and reactance, and is expressed in ohms. Apparent power is the vector sum of true power and reactive power, and is expressed in volt amperes.Apparent power is also the product of the square of the load current and the impedance of the load.
What is input impedance of a circuit?
Impedance is the total opposition to current flow. It includes both resistance AND reactance (capacitive and inductive). Impedance varies with frequency, while plain resistance does not. Scroll down to related links and look at: "Different names for the two impedances Z1 and Z2" "Calculation the damping of impedance bridging or power matching an interface connecting Zout and Zin" "Impedance bridging or voltage bridging of two audio units".
What is different between construction and fabrication?
Construction- building trade, make up of combined components. Fabrication-made up falsehood.
3 components of DNA?
The three components of DNA are phosphate, deoxyribose sugar, and nitrogen base. A DNA strand looks like a ladder. The "sides" of the ladder are made up by the phosphates and deoxyribose sugars the "steps" are the nitrogen bases.
What are three main components that make up a circuit?
The power source, the thing it's turning on, and the wire to connect the power to the thing.
