The 240 v air conditioning motor at a residence is rated at i hp with a power factor of 0.65 (lagging). determine the equivalent (a) impedance and (b) admittance of the ac motor.

(a) 50.20 ohm (b)

Explanation:

e have given the power P =1 hp =745.7 W

Voltage V =240 V

Power factor

We know that power

So

i =4.7801 A

Now according to ohm's law

(a) So

(b) Admittance of any circuit is the inverse of the impedance

So admittance    

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
