What else can I help you with?
Is loading effect more when load impedance is less then source impedance?
The higher the mismatch between the load impedance and source impedance, the higher the loading effect.
What is better 16 or 18 gauge stainless steel?
It really depends on what you're going to do with it. If you're making a sink you want 16 gauge because it's thicker and harder to punch holes in. If you're making a car hood, you want 18 gauge because it weighs less.
Why is the voltage at the end of a long extension lead used with an electric drill less than the mains supply voltage?
Resistance in the length of wire that makes up the extension cord causes voltage to drop. But it needn't be a problem with the right extension cord. For an electric drill, up to a 25 foot cord of 16 gauge wire will cause a voltage drop so small as to be negligible. For 50 feet, switch to a 14 gauge cord. For heavier power tools (circular saw in particular) you should use a 14 gauge extension from the get-go.
Is Common emitter configuration has high input impedance or medium input impedance?
Slightly less than cc configuration but greater than cb
Why impedance relay is called as distance relay?
because the distance is propotional to the impedance of the line ,so the operation of the impedance relay comes into picture when the impedance seen by the relay is less than the pre-setting value.When a fault occurs ,the current increases to a high value and so the Impedence decreases and the relay actuates
Is loading effect more when load impedance is less then source impedance?
The higher the mismatch between the load impedance and source impedance, the higher the loading effect.
What is the recommended length and type of extension cord to use for a dryer plug extension cord?
The recommended length for a dryer plug extension cord is 25 feet or less, and it should be a heavy-duty, 10-gauge wire extension cord to handle the high power requirements of a dryer.
What wire gauge used for headphones?
The wire gauge in thin headphone cables is quite small. I have read of people rewiring their headphones using 12 Gauge wire. There are commercial cables that use 11 gauge. The thicker the wire the less the resistance up to a point. Many headphones use 22 or 24 gauge and it seems to work OK.

What are the advantages of using a low impedance microphone compared to a high impedance microphone?
A low impedance microphone has better signal quality, less interference, and can transmit audio over longer distances compared to a high impedance microphone.

Can you connect a 6 outlet power bar to an extension cord?
There are several variables:First and most important, what will be the current draw? If the total number of amps exceeds the rating of either the power strip or the extension cord you're creating a fire hazard.Second, the wire gauge and length of the extension are important. You will loose voltage over distance and that is a function of the current draw, wire type and wire gauge. If you're trying to run 20 amps, don't use any less than a 12 gauge extension cord up to a maximum of 100 Ft. 15 amps, minimum 14 gauge.
Is Common emitter configuration has high input impedance or medium input impedance?
Slightly less than cc configuration but greater than cb
What is a tube microphone?
The tube or the FET transistor is used to build an impedance converter from the high impedance of the capacitor (condenser) of about 1 Giga ohms or more to the low impedance of the microphone output, which is less than 150 ohms.
What is the relationship between frequency and the size of a transformer?
Basically the characteristics of a transformer depends on the impedance(resistance) and on the coupling of its primary and secondary coils. The impedance of a coil depends on the frequency, as the frequency increases you need less volume of iron core and less number of turns in the coil for a given impedance, then reducing the size of the transformer.
Can an extension cord be to large for any appliance?
If you are talking about the gauge of the wires, then no. Larger guage wires( numerically lower) will pass current required for the appliance with lower losses, so it is better in that reguard Less resistance= less waste( in the form of heat). If you are talking about LENGTH, then yes. The longer the cord, the more losses that occur. Voltage lowers, so current goes up. If the extension cord can't pass the required current, then voltage remains depressed, and you end up with an appliance and extension cord that are running hotter, and less efficient. Worst case; fire.
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.
