What is passive antenna?
A passive antenna is an antenna that is not powered by an amplifier.
What is active devices?
An active device amplifies the signal by some value - such as an active filter using an OPAMP. A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.
What is a monolithic entity?
A monolithic entity is a type of integrated circuit used in electrical engineering. It has both active and passive devices.
Is a thermocouple an active or passive transducer-why?

A potentiometer is a active device or passive device?
passive
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.
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.
What is passive antenna?
A passive antenna is an antenna that is not powered by an amplifier.
Are capacitors active or passsive devices?
A capacitor is to electricity as a glass is to water. Both are passive devices, they can be filled and they can be emptied.
What is active devices?
An active device amplifies the signal by some value - such as an active filter using an OPAMP. A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.
Is an antenna active device?
In electronics any device that just pass along a signal by its characteristics is defined as passive.
What is the difference between an active antenna and a standard antenna?
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
Is active or passive transport hypertonic?
passive
What is the difference between active and passive component?
Active means devices that perform functions in a non linear fashion [amplifiers] passive are components that perform according to a set of linear rules
What three methods or devices are used to cool a CPU?
Passive and active air cooling and liquid cooling. What three methods or devices are used to cool a CPU
The teacher called the children is it passive or active?
active and passive
Why is an inductor called as passive device where as a resistor is called active device?
They are both passive devices. An active device is a device that uses semiconductors (or tubes) to process signals instead of using the natural processes of capacitance, inductance or resistance.
