Is antenna passive or active component?
An active antenna is an antenna which has an amplifier attached very closely to it. The antenna/amplifier system is called an active antenna. It is used for receiving signals only. The idea is to set the signal-to-noise ratio (SNR) before the signal travels along a transmission line where it is susceptible to interference and loss.
Can you use transformer in place of amplifier?
A transformer is a passive device while an amplifier is an active device. a transformer can amplify voltage but never power WHILE AN AMPLIFIER CAN amplify power's can you use it sure withing the limitation of the transformer and only to amplify volts.

Why you use resistor in amplifier circuit?
Resistors come under passive electronic components and are extensively used in electronic circuits. So important are these components that it may be virtually impossible to build an amplifier circuit without involving resistors. Basically the function of a resistor is always to oppose the flow of current through it and the strength of this opposition is termed as its resistance.
What is the difference between normal amplifier and magnetic amplifier?
normal amplifier is a mathametical operation analog the computer, magnetic amplifier is sound operation of the signal
What is passive antenna?
A passive antenna is an antenna that is not powered by an amplifier.
What are Passive components and its characteristics?
A passive component does not interact as an active component like an amplifier
Antenna is a Active or passive devices?
it depends on existing amplifier or not , if after antenna there's an amplifier it called active else it called passive which less sensitive that active .
If you have a sub woofer do you need an amplifier?
There are two types of subwoofers. 1. Active subwoofers 2. Passive subwoofers An active subwoofer will have a built-in amplifier. A passive subwoofer doesn't have a built-in amplifier which will require the use of an amplifier, the use of a power source.
Why is subwoofer cutting out?
It seems like you're using a passive subwoofer. A passive subwoofer doesn't have a power source (an amplifier.) You will need an amplifier for your subwoofer. Let a professional set it up for you.
Will an unpowered subwoofer work when plugged into an amplifier?
A passive sub-woofer does work when plugged in to an amplifier. In an active sub-woofer ("powered") the amplifier is built in.
What does subwoofer types like passive mean?
Passive subwoofers have an external amplifier. Active subwoofers include a built in amplifier. Top of the line home installations are typically always "active" but professional audio solutions often still use passive subwoofers.
Is an Aeriel on the roof a standard or an active antenna?
An active antenna is powered antenna, this includes a RF amplifier and a power supply so it must be "plugged in" somewhere. A standard "passive" antenna has no amplifier.
Can you connect a normal bass speaker to a system that has an active sub out put?
An output for an active sub-bass unit is a line level signal, typically around a volt or so. It won't drive a speaker directly so an active sub incorporates and amplifier to drive the loudspeaker. The way to use a passive bass speaker is to take the sub output into another amplifier and use one channel of the amplifier to drive the passive speaker. It's an easy solution if there happens to be a spare amplifier at hand. If it will involve the purchase of a new amplifier, it may prove more cost effective to buy an active sub-bass unit instead. However, passive bass drivers tend to be used in higher quality systems so it might offer a great quality sound with a good amplifier.

What are the big speakers at a concert called?
They are called "PA" speakers. PA meaning "Public Address" is a large loudspeaker design to deliver sound to a large group of audience. You'll often see these large speakers at clubs, concerts, and cinemas. There are two types of PA speakers. "Passive" and "Active" speakers. The passive speakers doesn't have a built-in amplifier. These speakers will require the use of a power source called an "Amplifier" to power these speakers. The active speakers have a built-in amplifier and doesn't require the use of an amplifier.
Do all subwoofers have their own power source?
Most subwoofers have their own power source. There are subwoofers called "passive" woofers that will be powered by your amplifier.
