What is the inverse of transconductance?
Roughly speaking, resistance. Transconductance refers to the reciprocal of the amplifying device's internal resistance. The concept is particularly useful if the device is a voltage-controlled current source (tube or FET). In vacuum tube amplifiers, transconductance (Gm) is (u / Rp), where... u is the amplification factor. u= (Gm x Rp). Rp is the anode (drain) resistance. Rp is the internal resistance of the amplifying device. Gfs is synonymous with Gm. The reciprocal of Gm (or Gfs) is (Rp / u). Another term for this reciprocal is transresistance.
What was the first electrical invention?
Before the famous Light Bulb, in 1762, Johan Carl Wilcke described the electrophorus, a device for generating electricity [see Wikipedia for more details].
When was Central Electricity Generating Board created?
Central Electricity Generating Board was created in 1957.
Suggest another circuit for generating the ASK signal?
suggest another circiut for generating the ASK signal
How are synchros used in error detection?
Control systems are synchros which are used in error detection. They provide a voltage to be converted to torque through an amplifying method.
Device for generating and ampifying microwaves?
a maser
What kinds of filters use some type of amplifying device?
Active filters.
Why are there microwaves instead of radio waves in a mobile device?
your mum :D
What is a device that produces clicking sounds or flashing light by amplifying an electric current formes when radiation is present?
A Geiger Counter
What is a device that produces clicking sounds or flashing light by amplifying an electric current formed when radiation is present?
A Geiger Counter
What is a RF amplifier?
A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
Which network device has the capability of amplifying and regenerating network signals but has no capability of routing or segmenting?
I would say an ethernet extender/booster/repeater.
How do you change the loudness of a sound?
By making adjustments to whatever device is generating the sound.
Which type of electromagnetic wave would be most useful for a device to warm food safely?
Microwaves
Device that produces clicking sounds or flashing light by amplifying an electric current formed when radiation is present?
A Geiger meter satisfies those requirements.
Was the first amplifying tube a triode?
If by triode, you mean "a three-electrode tube", then yes. You need a source of current into the device, a control electrode, and an "outlet" for the controlled current. Although there were radically different types of construction, all early amplifying tubes were triodes of some kind.
How are microwaves magnetic?
Inside a microwave oven,microwaves are made when electricity passes through a device called Magnetron.Magnetron uses a strong magnet. The electricity and the magnet make microwave electromagnetic.
