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.

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.
What is a device for generating or amplifying microwaves?
A magnetron is a device commonly used for generating microwaves in microwave ovens. It works by utilizing the interaction of electrons with a magnetic field to produce electromagnetic waves at microwave frequencies.
Device for generating and ampifying microwaves?
a maser
What are microwaves and how do they work in microwave ovens?
Microwaves are a type of electromagnetic radiation that have a short wavelength. In microwave ovens, these microwaves are produced by a device called a magnetron. The microwaves are then directed into the oven cavity where they cause water molecules in the food to vibrate, generating heat and cooking the food quickly and efficiently.
Divice for generating and amplifying microwaves?
A microwave generator typically consists of a magnetron, which converts electrical energy into microwave radiation. The microwaves produced can then be amplified using a microwave amplifier, such as a traveling wave tube (TWT) or a solid-state amplifier. These devices are commonly used in radar systems, communication equipment, and microwave ovens.
How do microwaves heat water?
Microwaves heat water by causing the water molecules to vibrate rapidly, generating heat through friction.
What kinds of filters use some type of amplifying device?
Active filters.
How do microwaves give off radiation?
Microwaves emit electromagnetic radiation in the form of microwaves when they are turned on. This radiation is absorbed by food and causes water molecules in the food to vibrate, generating heat that cooks the food.
What is a device to generate and amplify microwaves?
A device used to generate and amplify microwaves is a microwave magnetron. This electronic vacuum tube generates microwaves using the interaction of electrons with a magnetic field. The generated microwaves are then amplified within the device before being emitted for various applications such as cooking in microwave ovens or communication in radar systems.
How do microwaves heat food?
Microwaves heat food by emitting electromagnetic waves that cause water molecules in the food to vibrate, generating heat through friction.
Do microwaves cook food from the inside out?
Microwaves cook food by causing water molecules inside the food to vibrate, generating heat. This heat cooks the food from the inside out.
What do microwaves do when they are used to heat food?
When microwaves are used to heat food, they cause water molecules in the food to vibrate rapidly, generating heat and warming up the food quickly.
What is one example of microwaves?
One example of microwaves is the electromagnetic radiation emitted by microwave ovens. These microwaves heat up food quickly and efficiently by causing water molecules to vibrate, generating heat in the process.
