    Power Power factor
AI Thread Summary
To find the apparent power (S) and power factor (pf) for a load operating at 125V-rms with 55W of real power and 26VAR of reactive power, the calculations yield S = 60.8 VA and pf = 0.90. The apparent power is calculated using the formula S = sqrt(P^2 + Q^2). The power factor, indicating the load's nature, is derived from pf = P / S. Since the load absorbs positive reactive power, it is classified as lagging. The calculations confirm the values are correct.

Homework Statement



A load operates at a voltage of Vx = 125V-rms and absorbs P = 55W andQ = 26VAR of power. Use this information to calculate the apparent power (S) and the power factor (pf) for the load.

Homework Equations



S = sqrt [ P^2 + Q^2]
pf = P / S


The Attempt at a Solution



S=60.8 VA
pf=.90

Looks good. Maybe include:
pf = 0.90 lagging

since your load is inductive (it absorbs positive reactive power).
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
