What is the difference between photosystem one and two?
The difference between photosystem one and two is their type of light reaction.
Which type of energy is transferred due to a temperature difference?
heat
Is there a difference between edge triggering and pulse triggering?
Edge triggering is one type of pulse triggering. The other type is level triggering.
What factors are considered in the selection of dc machine?
The initial factors are the working voltage and power level required. These set the size of the machine. There are three types of dc machine depending on how the internal magnetic field is produced. A permanent magnet machine gives a constant excitation field and is preferred for smaller motors since no field winding is needed and the machine is therefore simpler. A shunt-wound machine has the field winding in parallel with the armature (the rotating part) and is the commonest type of dc machine. This is used for high-power motors or generators (they are the same thing) where the speed of operation is fairly constant. A series-wound machine has the field winding in series with the armature. This type is used in traction, to drive trams and trolley-buses. The torque produced by a dc machine is proportional to the field current and also to the armature current, so a series motor produces torque proportional to the square of the current. When starting, the motor draws a high current limited only by the resistance in circuit, so the torque is very high and suitable for starting the vehicle. A switched starting-resistor keeps the current within limits. A standard shunt-wound motor acts as a motor when a mechanical load is applied, but if the motor is driven faster than it rotates naturally without a load, then power flows back into the supply and it becomes a generator. A shunt-wound motor tends to behave as a capacitor because the starting current is high and it then reduces exponentially as the rotor gathers speed. If the supply is disconnected, the terminal voltage reduces exponentially as the speed runs down. In a capacitor the energy is stored in the electric field while in the dc machine it is in the kinetic energy of the rotor.
What is the difference between invincible and invisible?
Type your answer here... invincible is when you cant get hurt and invisible is when noone can see you
What type of voltage regulators r there?
series and shunt voltage regulators
What is pmmc type of instruments?
Produce of series type Ohmmeter using PMMC of Ifsd:100uA for range of 0-20kohm?
Difference between amplifier and feedback amplifier?
An ordinary amplifier can have high gain but is unstable, drifts, can oscillate, etc. An amplifier with negative feedback has lower gain but is stable, does not drift, won't oscillate, etc.
What is difference between stab shunt dc motor and shunt dc motor?
A series motor respond by decreasing its speed with small increase in current for a given load torque. A shunt motor holds its speed nearly constant with large increase in input current for same amount of load torque
What is DC shunt motor?
A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. This type of motor has good speed regulation even as the load varies, but does not have the starting torque of a series DC motor
What type of meter uses its own battery?
Ohmmeter
What is ohmmeter?
An ohmmeter is a type of electrical metre that measures electrical resistance. When in resistance-measuring mode, multimeters also operate as ohmmeters. An ohmmeter measures the resistance of a circuit or component by passing electricity through it.
Can you fly if you have a shunt?
i heard u can fly on short journeys Yes, you can fly if you have a shunt, however the affects, as far as the pressurized cabin goes will depend on the type of shunt you have. I have a VP shunt in my head and have no trouble flying and I fly often, as I work for an airline.
What is the best type of motor for escalator?
DC Shunt motor
What type of motor is used in a conveyor?
dc shunt motors
What is the difference between Lenovo t series and Lenovo s series?
The difference between the Lenovo T series and the Lenovo S series is the type of laptop. The Lenovo S series is a laptop, while the Levnovo T series is a tablet.
Did Ice T narration for money ball?
A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. This type of motor has good speed regulation even as the load varies, but does not have the starting torque of a series DC motor
