Question

The input of an ac circuit having p.F. Of 0.8 lagging is 20 kva. The power drawn by the circuit is __________ kw.

Answer 1

Answer: hi friend

ANSWER IS 16

 EXPLAIN  

KVA=VI*10^3

Power=VI*PF

Powerdrawn=KVA*PF=20*0.8=16KW

Answer 2

The power drawn by the circuit is 16 kw

Step-by-Step Explanation:

Given:

P.F. of Circuit- 0.8

Lagging-20kva.

To Find: the power drained by the circuit.

Formula

$kVA=\frac{Kw}{cos}$Ф

$kVAR=(kVA)(sin$

$sin$Ф=$\sqrt{1-cos^{2 }$Ф

where,

kVA= apparent power(s)

kW= active power(p)

kVAR= reactive power(q)

cosФ=power factor

In an A.C. circuit, true power drawn by the circuit is given by:

True power = Apparent power × Power factor

Solution:

Here, input apparent power is 20 kVA and the power factor is 0.8

The power drawn by the circuit is:

$(20*0.8)kW$

$16kW$.
