Question

Calculate the power factor of coil having resistance of 24 Ω draws the current of 5A at 240V/ 50HZ AC supply. ​

Answer 1

Answer:

1

Step-by-step explanation:

Power factor is

$cos \alpha$

$cos \alpha = \frac{r}{z}$

Where r is the resistance

z is the impedance.

Since nothing is connected in series with these resistor, z=r.

So, power factor,

$cos \alpha = \frac{24}{24 } = 1$
