What is frequency domain counterpart of convolution?
Convolution in the time domain is equivalent to multiplication in the frequency domain.
When current in primary coil decreases current in the secondary coil also decreases?
It is reverse. when load current in the secondary changes the primary current also changes directly. Load current is dependent on the load.
I am assuming that the question is related to a normal distribution transformer.
What is the voltage across a 1k ohm resistor when it dissipates 0.625w?
dude... using the relation power is the ratio of square of voltage to the resistance
P=V^2/R
on substitutiing ,
we get v=(0.000625)^1/2
= 0.125 V
The same as what? when an inductor is connected in series with a resistor and a current passed through them, the voltages across the resistor and inductor are equal when the reactance is equal to the resistance:
2.pi.f.L = R
Who collector base current when emitter is off?
When the emitter of a bipolar junction transistor (BJT) is off, the collector-base junction is typically reverse-biased, meaning that the collector current is minimal or negligible. In this state, the collector-base junction does not conduct significant current because the emitter does not provide carriers to the base. As a result, the collector current is effectively zero, and the transistor is in its cutoff region.
What is safety guard for blind using 555 timer?
A safety guard for the blind using a 555 timer typically involves creating a device that can detect obstacles and provide audio or tactile feedback. The 555 timer can be configured in a monostable or astable mode to control sensors, such as ultrasonic or infrared, which measure distances to nearby objects. When an object is detected within a certain range, the timer triggers an alert mechanism, such as a buzzer or vibration motor, to warn the user. This setup enhances mobility and safety for visually impaired individuals by providing real-time alerts about their surroundings.
What is the difference between transfer function and frequency transfer function?
frequency transfer function deals with transfer in frequency domain, transfer function alone can be referring to any type of transfer in different domain e.g time domain
Can a 5v battery charger be used to charge a 3.7 v battery?
Last night I took my zen vision w which has a 3.7v battery and i tried to charge it with a 5v usb wall charger. At first it was charging normally, my zen even turned on, when I came home from walking the dogs my zens screen was black and the blue light just flashed five times every time i tried to turn it on. So I guess the answer is no, i guess i blew a cuircuit. I feel horrible...
What is the explanation for the types of Switching systems?
There are three type of switching system such as circuit switching ,packet switching , massage switching.
Constant current generation of linear sweep voltage using op-amp?
When using the Op-amp we get constant current generation of the linear sweep voltage.
Where do you set meter when checking for ripple?
When checking for ripple on a power supply, you should set the meter to the AC voltage setting. Connect the meter probes across the output terminals of the power supply while it is under load, if possible. This allows you to measure any AC voltage fluctuations (ripple) superimposed on the DC output. Ensure that the range is appropriate for the expected ripple voltage level.
In rectifiers, a filter is a circuit component or arrangement used to smooth out the output voltage by reducing the ripple voltage after the rectification process. It typically consists of capacitors, inductors, or a combination of both that store and release energy, maintaining a more constant DC output. This smoothing is essential for ensuring that the power supply delivers a stable voltage to electronic devices, improving their performance and longevity.
How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
