In an ideal AC distribution system, what power factor is assumed?

Answer & step-by-step solution
Correct answer: B. Unity
Quick explanation

B — Unity. An ideal AC distribution system is usually assumed to operate at unity power factor, so there is no reactive current and minimum loss.

Detailed solution (in the paper’s original language)

સમજૂતી

Ideal AC distribution system માટે સામાન્ય રીતે unity power factor ધારવામાં આવે છે.

Unity power factor પર idealized condition માં reactive-power demand શૂન્ય હોય છે અને નિર્ધારિત real power તથા voltage માટે current minimum રહે છે.

મુખ્ય ખ્યાલ

Ideal AC system → power factor = 1.

સૂત્ર

PF = cosφ = 1 ⇒ φ = 0°.

પરીક્ષા મુદ્દો

'Ideal' શબ્દ ખાસ ધ્યાનથી વાંચો.

ઝડપી ટ્રિક

Ideal simplified model માં reactive component માનવામાં આવતું નથી.

બીજા વિકલ્પો ખોટા કેમ છે

0.9 lagging practical value હોઈ શકે છે, ideal assumption નહીં.

સામાન્ય ભૂલ

Practical lagging PF ને ideal PF સમજી લેવો.
