What is current value after derating factor considered?
Once derating factor is considered the size of cable for perticular electrical load increased by the multipling factor.i,e if 2.5MM2 cable is capable to carry 14amp. of current in general then with 40% of derating fator it can carry only 8.4amp.
What is derating factor in case of diesel engines?
air flow speed
The calculation used to determine amperage of a conductor based on the total number of conductors in a conduit is called A derating B voltage drop C conduit fill D conductor fill?
derating
What is the ripple factor of full wave rectifier?
although the AC signal is rectified the output which we get is the pulsating DC which is not desired because many appliances wok on plain DC voltage . The pulsating DC can be viewed as AC + DC component of the signal ripple factor of a rectified circuit is the ratio of AC component of signal to the DC component of the same rectified output signal. higher the ripple factor says that the signal is not smooth so lesser is its application. the components used to smooth these type of signals or to remove the 'ripple voltage' as called filters
Where would DC be used instead of AC?
DC is used for extra-high voltage transmission systems, as there are less losses with DC than with AC, and no synchronising problems.
What is derating factor of battery?
batteries derating factor will change ,depends upon the temperature& cable size which arelinked with batteries bank.

derating
Why DC current used largely?
in case of dc losses are very less than in case ac,as power factor is 1
What is the meaning of derating factor?
A transistor rating that tells how much the maximum allowable value of PD decreased for each 1°C rise in ambient temperature.
Power factor of dc ballast is 0.8. what will be the power factor same ballast in AC?
Power factor is an AC only term, and has no meaning for DC.
How many current carrying conductors are allowed in a raceway before derating?
You can put three ccc's in a conduit (any size conduit) before you derate. Keep in mind that for single phase loads (lighting, receptacles) the neutral is also counted as a current carrying conductor. This derating factor does not apply to nipples 24 inches long or less. See NEC Table 310.15(B)(2)(a) for full details on derating regarding ccc's.
What is the derating?
Derating factor depends on ambient temperature & how u r laying the cable ie., in Air,Duct,Burried. normally the current carring capacity of a perticular cable is calculated at 40*c, but if u lay the cable in air then it includes the temparture around it,if it increases more the 40*c then the conductor gets heated up by increasing the resistance in it thus the current carring capacity of a given cable decreases, so we will derate the cable The derating factor of induction motor is the ratio of the calculated output power to the rated power
Why dc source is used for dc supply?
it is only work on it so that used
What DC motor is used for traction?
dc series motor is used for traction...
