Why does the frequency of the forward channel is greater than the freq of the reverse channel in mobile comm?
I may be missing something here, along the lines of a definition, but
isn't the 'forward' channel at one end of the link the 'reverse' channel
at the other end, and isn't the 'reverse' channel at the first end the
'forward' channel at the opposite end ?
its just a convention used in cellular systems.
One voltage is greater in thyristor whether forward breakover or reverse breakdown voltage. The greater of the two voltages in thyristor is forward breakover voltage.
the rate of the forward reaction is greater than the rate of the reverse reaction.
forward breakover voltage is slightly smaller than reverse breakdown voltage
If the gate-channel junction of a JFET was not reverse biased the JFET would just act as a forward biased diode across that junction and the gate would cease to have any control over the channel conductance. For the same reason in a MOSFET the substrate-source/channel/drain junction must remain reverse biased. The MOSFET could not act as a MOSFET.
In a JFET the only insulation between the gate and the channel is a reverse biased diode junction, if this junction becomes forward biased then the gate and channel are effectively shorted and the device no longer acts as a transistor (it will act as a forward biased diode instead). In the n-channel JFET, the gate is the P-side of this diode and the channel is the N-side of this diode. To keep this diode… Read More
has a full charge won't go forward or reverse
the differences between UJT and FET are :- 1. structural :- a. there is only one p-channel in the UJT where as two in JFET b. the p-channel of UJT is more highly doped when compared to p-channel in JFET 2. functional :- UJT always works in forward biased condition (gate is forward biased) where as JFET always work in rverse bias condition (gate is reverse biased)
Yes, if there is only one forward and one reverse reaction.
The ammeter is connected in different way in forward and reverse bias zenner diode. So that all of the board will work right going forward and reverse.
The most important specifications of a diode are: maximum forward current peak inverse voltage (aka maximum reverse voltage) reverse leakage current reverse turnoff time (very important in high speed switching diodes) maximum power dissipation (only given for power rectifier diodes) forward bias knee voltage parasitic capacitance (only important in high frequency applications) All of this and more can be found in the datasheet for the diode.
truck will only go forward not in reverse does this mean the transmission is gone
macroscopic characteristics of both forward and reverse reactions
In a chemical system, there are forward and reverse reactions occurring constantly. As the forward reactions progress, the increased amount of products allows for more and more reverse reactions. Once the rate of the forward and reverse reactions are equal, the system is at equilibrium. The forward and reverse reactions continue at equal but opposite rates; however, there are no further changes in the concentration of the products and reactants.
chemical equilibrium is where forward and reverse reactions occurs in a same rate or in equal rate.... or rate(forward) = rate(reverse)
For chemical equilibrium Rate of forward reaction + Rate of reverse reaction = zero
What would cause the 1995 Nissan Pathfinder not to go in forward or reverse?
A forward reverse star delta is a two in one motor starter where a motor first runs on star connection and then changed to delta connection after a time which has been set. The motor direction can be changed, whether forward or reverse
you want to keep the channel electrically isolated from the gate (jfet) or substrate (mosfet) so that it operates as a fet, don't you? if it was forward biased it would just be a diode with no field effect.

A reverse idler gear in a manual transmission. It converts the reverse gears turning direction into the outputshaft to reverse its direction. The transmission can not spin clockwise when the reverse idler is engaged thus it only spins backwards not forward.
Forward Resistance: def: It is resistance offered by diode to the forward bias is known as forward resistance. This resistance is not the same for the flow of DC as for the changing current. Accordingly this resistance is of two types : 1. DC FORWARD RESISTANCE. 2. AC FORWARD RESISTANCE. 1. DC forward resistance: It is the opposition by diode to the DC. It is measured by the ratio of DC voltages across the diode… Read More
A forward biased diode conducts current, while a reverse biased diode does not allow any current to flow.
car will jerk forward and then go in reverse
to determine the comparison of resistance value of both forward and reverse diode . The more the resistance the lower the current , the lower the resistance the higher the current . When reverse bias , the resistance is high and it acts in open circuit and the reverse current is very small that can be neglected . When forward bias , the resistance is low and it acts as short circuit and the forward… Read More
Forward lookup is name-to-IP address; the reverse lookup is IP address-to-name.
The reverse on a waverunner works very similarly to the reverse on a jet plane. A mechanism called a "reverse gate" drops down over the jet on the back of the Waverunner. The reverse gate changes the direction of the thrust so that it goes forward instead of backward. With the thrust going forward, the Waverunner goes backward for the same reason it goes forward with the thurst going backward. Note that switching into reverse… Read More
Electric corkscrews usually have both a forward and reverse option. Use forward to pull the cork from the bottle, and reverse to remove it from the screw.
transistor is a nonlinear device. it will acts as a swicth based on the cut in voltage we can easily identifying the the transistor is in forward or reverse bias.in forward it is 'on' reverse bias 'off'.
The antonym for forward is backward, but the opposite direction can be reverse or rearward.
a diode has two junctions one is doped with p-type and another is doped with n-type.a diode connected in reverse bias means that the n-channel is connected to the positive end of the battery and p-channel is attached to the negative end of the battery if we start increasing the reverse voltage the width of depletion region increases and the exchange of charge carriers (holes and electrons) is inhibited so we expect zero current in… Read More
Because the insulation between the gate and the channel is only a reverse biased PN junction. If this junction were to become forward biased the jfet would no longer operate as a transistor at those times.
capacitive diodes run in the reverse mode

Would extreem clutch slipping in first but not reverse after a transmission rebuild indicate a worn out clutch or a problem with the success of the transmission rebuild?
If no forward or slipping forward suspect problem in the forward clutch and circuit. Reverse does not use the same applied components
Same as forward but... Backwards
forward bias is in the direction a junction or vacuum tube wants to conduct current reverse bias is in the direction a junction or vacuum tube opposes conducting current
If you mean the transmission itself shifts forward, it is because the transmission is suspended, so when the transmission is put in reverse gear the momentum will push the transmission forward. Now, if the car pulls forward when put in reverse, this means there is a transmission problem. This may just indicate the shift linkages need adjustment, or that the transmission has a major problem and needs repairing. Take it to a shop and have… Read More
interchange T5 and T8 to reverse rotation...
When the polarity of the battery is such that electrons are allowed to flow through the diode,then the diode is said to be forward-biased. Conversely, when the battery is "backward" and the diode blocks current, then the diode is said to be reverse-biased. A diode may be thought of as like a switch: "closed" when forward-biased and "open" when reverse-biased.
The question should be like: How can a transistor be used as an amplifier...?? Answer: There are four mode of operations for a transisitor. 1. Forward active mode. 2. Reverse active mode. 3. Cut Off mode. 4. Saturation Mode. To be an amplifier, transistor must be used in forward active mode. To understand the modes, lets consider a pnp/npn transistor. In forward active mode, Emitter-Base Junction is forward biased & Collectror-Base Junction is reverse Biased… Read More
A: a diode will not emit photons will have greater reverse voltage breakdown will conduct large amount of current its voltage drop can be predicted to be .6-.7 volts. LED will emit photon when excited will have a low voltage reverse breakdown because of its hi forward voltage drop the current will be into the ma range
When a Mercedes C280 will not move in forward or reverse it is an indication that the transmission is going out or has already gone out in the car. This is true of all cars, not just a Mercedes.
A: Forward bias is a scheme to bias a device so that it will conduct riding this bias voltage. a reverse bias is a voltage to keep a circuit off or not conducting.
