Do we have to learn the working of a generator?

Active member

the diagram I think is sufficient

for generators we hv to do its principle,description,theory and uses.....

Yes we ahve to learn the working of a generator.... Crying or Very sad

Active member

what?? but the syllabus is only what Kool posted in the previous reply...so we don't have the working.....anyway do we have to learn q-factor??

Active member

no we dont hv to do q factor...............
only power factor is there..................

Active member

ok..ty..and can you post some notes on phasor diagrams? Smile

...i can't understand it in my text book. Crying or Very sad

Active member

u can visit this site if u get any help.....
thn let me know....

i went through the link you posted...but it does not contain info regarding what we need to kno for the isc...

Active member

which book do u use????????

Phasor Diagrams

It is sometimes helpful to treat the phase as if it defined a vector in a plane. The usual reference for zero phase is taken to be the positive x-axis and is associated with the resistor since the voltage and current associated with the resistor are in phase. The length of the phasor is proportional to the magnitude of the quantity represented, and its angle represents its phase relative to that of the current through the resistor. The phasor diagram for the RLC series circuit shows the main features.
Electromagnetism Phas2

Note that the phase angle, the difference in phase between the voltage and the current in an AC circuit, is the phase angle associated with the impedance Z of the circuit.
