In AC, impedance (Z) takes on real and imaginary components, and so do voltage (V) and current (I). Re(Z) is affected the DC resistance. Im(Z) is determined by the capacitive and inductive components of the circuit.

State three things which can affect the voltage in a circuit?

Ohms Law says that Voltage = Current * Ohms, so the twothings that can affect the voltage in a circuit are Current and Ohms. If have a non resistive impedance, i.e. a capacitor or inductor forming a reactance, then frequency can also affect the voltage but, mathematicaly, reactance is a frequency domain form of impedance, so my answer stands - Current and Ohms.


In a two stage amplifier does the input impedance of the second stage affect the voltage gain of the first stage?

as i understand this impedance is something that impedes, or adds resistance or something like that. ( There are impedance bonds on the railroad to divide the track up into sections for signal purposes) by words, you see the connection with impede and impediment. the impedance, like resistance, would have to be a factor to be reckoned with. I am only familiar with Impedance bonds-they are laid horizontally under the track structure, and are part of the signal system.


What is analog audio impedance?

To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.

How does frequency affect power?

Frequency does not directly affect power. Power is determined by the voltage and current in a circuit, which are influenced by factors such as resistance and reactance. However, in some cases, changes in frequency can impact the impedance of a circuit, affecting the power consumption.


What are the differences between low impedance and high impedance, and how do they affect the performance of electronic devices?

Impedance refers to the opposition of a circuit to the flow of alternating current. Low impedance means there is less opposition, allowing more current to flow easily. High impedance means there is more opposition, limiting the flow of current. In electronic devices, low impedance can lead to better performance and efficiency, while high impedance can cause signal loss, distortion, and reduced overall performance.


Which is better high input impedance or low input impedance and why?

That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.

What is the significance of impedance in electrical circuits and how does it affect the flow of current?

Impedance in electrical circuits is important because it measures the opposition to the flow of alternating current. It consists of resistance and reactance, which affect how current flows through a circuit. A higher impedance means there is more resistance to the current flow, which can limit the amount of current that can pass through the circuit. This can impact the efficiency and performance of the circuit.


How to distinguish between characteristic impedance and input impedance?
