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 vernier potentiometer?
A variable resistive device
Is a thermocouple an active or passive transducer-why?
is a thermocouple an active or passive transducer?-why?
Which one is better potentiometer or voltmeter?
Neither is better or worse than the other. A potentiometer is an adjusting device usually for voltage while a voltmeter is a device for measuring the voltage. They are just two different things.
Is the inductor a passive component or active component?
passive
Why potentiometer is called passive transducer?
because potentiometer generate a own current
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 relay active or passive?
diode is a two terminal passive non linear device.
What is the difference between active load and passive load?
Passive Load is Load comprising of Passive Components Active Load is the Load comprising of Active Components In Test Boards its better to use Active Loads, If you are concerned about Temperature Variations during characterisation
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.
What difference in electrical and electronic device?
A: The difference is PASSIVE / ACTIVE
Is relay an active or passive device?
Yes, it is an electrically operated switch.
Is diode an active or passive device?
An active device is a device that takes input energy to operate. The only energy a diode uses is from the signal applied to it (it has one input, one output, and no other terminals), so it is a passive device. To be an active device, a separate power source must be applied to it - such as the case for operation amplifiers, for example.
What is the device that produce gain active or passive?
Either. although a passive device can only produce gain from 0-1 (-inf to 0dB) an active device on the other hand is capable of producing gain thats greater than 1 (0dB)
Why active filters so called even though uses passive resistors?
It has to have resistors but an active filter will alsol have an active device, usually an op-amp, while a passive filter has only passive components and needs no power supply.
Is an antenna active device?
In electronics any device that just pass along a signal by its characteristics is defined as passive.
What are active elements in circuit?
A; Any components that provide gain/loss are active device resistors, capacitors are passive
