The average power dissipated in A.C. circuit is 2 watt. If a current flowing through a circuit is 2 A and impedance is $1\Omega$, what is the power factor of the AC circuit?

Solve :
$cos\left(\frac{dy}{dx}\right)=a,aϵR,y\left(o\right)=2$

Fill in the missing fraction
(a) $$\frac{7}{10} - \Box = \frac{3}{10}$$
(b) $$\Box - \frac{3}{21} = \frac{5}{21}$$
(c) $$\Box - \frac{3}{6} = \frac{3}{6}$$
(d) $$\Box + \frac{5}{27} = \frac{12}{27}$$

The self inductance of a choke coil is mH. when it is connected with a 10 VDC source then the loss of power is 20 watt. When it connected with 10 volt AC source loss of power is 10 watt. The frequency of AC source will bw-
