What is brownout?
Brownout reset is a circuit that forces the microprocessor to reset if there is a short interruption of power - one that is long enough to disrupt operation, but not long enough to force a normal power on reset. It is usually a diode, resistor, and capacitor. The diode discharges the capacitor quickly when Vcc goes away, and the resistor charges the capacitor slower when Vcc comes back.
What is diode rectifier?
By definiton, a diode lets electrical current flow only in one direction. A RECTIFIER DIODE is basically the same thing. It is used mainly for power supply operation and can handle higher current flow than a regular diode. Diodes are rated from milliamps to as high as 100 amps per diode depending upon the diode style and amperage rating. A recitifier diode is the same as a "Power diode". Diodes are mainly used to change AC (alternating current) into DC (directo current) which is used by batteries and etc.
What are uses of carbon film resistor?
Same as any other kind of resistor, they're used to control voltages and currents in electric circuits.
What is the difference between clippers and clampers in electronics?
Clippers are diode, wave-shaping circuits. The output of clipping circuits looks like a portion of the input signal is clipped off, kind of like a limiter. A clipping circuit requires at least two basic components, a simple diode and a resistor. The output wave form can be clipped at different levels by interchanging the position of the diode and or resistor, and changing the voltage of the dc battery.
What happens to leakage current of the diode when temperature changes?
The reverse-biased leakage of a diode is due to to two things. One, a physical property of the diode known as free-carrier recombination. The electrons and positrons which exist near the p-n boundary are constantly re-combining. This creates a fixed current known as the saturation current. If the diode is reverse biased, then the saturation current flows in the external circuit. Two, contamination in the diode causes a current which is like a resistor connected in parallel with the diode. A good rule of thumb is that the total reverse-biased diode leakage current (One + Two) will double every 10 degrees C. For the very best diodes, with tiny leakages, search for the forum comments of Dr. Winfield Hill on the topic of very clean diodes with ultra-low leakage.
How may type of resistors in diode?
None. A diode does not have a resistor in it. Diodes and resistors are different devices used for different purposes. For example, increasing current flow through a resistor increases the voltage drop across the resistor. Increasing current flow through a diode (within the diode's capabilities, just the same as a resistor) will actually decrease the voltage drop across the diode (once the diode "turns on" this voltage variance will be fairly small, though).
How much forward diode voltage is there with the ideal diode approximation?
Consider ideal diode to be connected in series with resistor of 6kSilicon diode forward bias voltage = 0.7 voltsCurrent across 6k resistor = (5-0.7)/6000 amperesVoltage across {resistor + diode}=4.3 + 0.7=5vIf silicon internal resistance is 6k then voltage across diode=5vIf external resistance is 6k and diode resistance is negligible then voltage across diode=0.7v
Are resistor and diode same in a radio transistor?
A resistor and a diode are not the same. A resistor reduces the amount of current going through a wire. It turns current into heat. A resistor does the same thing wherever it is be it in a radio or an electric stove. An element in an electric stove that you have seen glowing red is a great big resistor. The element in an electric light bulb is a resistor. A diode contains is a material that only allows electricity to pass through in one direction. They are not the same. However, when an engineer builds a radio circuit, there are problems between theory and practice. A resistor not only reduces the amount of current but causes impedance. A capacitor not only carries capacitance but also has a degree of resistance. A diode not only makes the current flow in one direction but has a certain amount of resistance in the process. After the engineer has designed the circuit, he builds it. Then because the parts have all different characteristics besides the expected ones, he tweaks it until it works.
What are the different types of semiconductor?
Transistor Diode Resistor Capacitor
Is diode an active device?
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
Can a resistor be mounted in either direction?
Yes, unlike a diode, a resistor is bi-directional (technically known as non-polarized)
How do you test blower motor resistor on a Dodge 2005 Grand Caravan?
Resistor is behind glove box (Push inward on glove box hinges to release) Pull out both sets of wires from resistor plug-in. (push release clips on both sets to pull out wires) Remove 2 small screws holding the resistor. Remove the resistor ( test the wire that has the small diode ) with a multimeter to ensure it has power on both sides of the diode. If there is current on your multmeter the resistor is okay...... if no current is present on your multimeter the diode is burnt and the resistor unit needs replacement.
What is the supply for a diode?
The diode voltage drop is 0.7 volts, so you need that much to turn it on. Current is controlled by a resistor in series.
What is the need of resistor in the experiment of pN junction diode?
The resistor limits current so you can measure voltage across the diode. When you forward bias and saturate a junction, the voltage across it will be constant (0.7 in silicon, for example).
Name four common parts of an electric circuit?
Transistor, resistor, diode, output.
Is pin diode and led diode are same?
no
Why the dynamic resistance of a zener diode different from its static resistance?
The dynamic resistance of a diode, be it zener or otherwise, will be different from its static resistance because a diode is not a resistor, and resistance is not a function of current flow. It is a diode, and a diode has its own characteristic voltage to current curve, forward and, in the case of a zener, reverse.
