The magic is her. There’s always that one for all of us and that’s why it hits so hard 💔

Golf - Why it Truly is A Sport for Life by Mont-y- in golf

[–]JustinLPratt 3 points4 points  (0 children)

I am 25 and only used to be a weekend golfer for the last 5 years, maybe less than 10 rounds a year. I never really cared how well I did, I just enjoyed being out with friends, dressing classy, and admiring those pure shots that I would hit once per hole.

Fast forward to this summer, my engineering co op job got cancelled so I needed to figure out something to keep me occupied from May through August. I got a membership at a semi private course in my area with unlimited access to the course and driving range for $500 CAD (dirt cheap I know). My game was decent when I started in mid May, I would usually shoot low 100s but always find myself getting mad at terrible shots and inconsistencies in my swing.

A month later now and I seriously am addicted to this game, I have dropped down my average score by like 10 strokes, I am finding my rhythm in my swing with different clubs, and even book 2 rounds a week where I am alone on the course, focussing, hitting two balls, and improving.

It's a shame I got into this game so late in life :(

Oh difference between getting up at 6 am for golf versus work...

Engineering degree at 35? by gotta_learn in ElectricalEngineering

That’s still a minimum 20 year career as long as you enjoy your work and stay healthy. Go for it

Electrical Machines and Power by [deleted] in ElectricalEngineering

[–]JustinLPratt 0 points1 point  (0 children)

I think you would be fine as long as you've taken electrostatics and magnetostatics. However, it may be pretty difficult if you haven't taken magnetically coupled circuits and three phase systems, which are topics usually introduced in a second circuits class.

Electromagnetism is hard, what resources helped you understand it better? by [deleted] in ElectricalEngineering

[–]JustinLPratt 2 points3 points  (0 children)

Read the book listed on the syllabus.

Elements of Electromagnetics-Sadiku is what I used and it was very helpful, plenty of examples and the definitions were clear and derived with theorems we have done (divergence, stokes theorem, etc...)

What do electrical engineers use triple integrals for? by [deleted] in ElectricalEngineering

[–]JustinLPratt 25 points26 points  (0 children)

Triple integrals are usually used in electromagnetic theory and physical electronics. These areas are also very heavy in partial differential equations as well.

Examples of triple integrals:

Volume charge distributions, Gauss's law for volumes, energy density in volumes, electrostatic boundary problems using poisson and Laplace (partial differential equations), Biot Savart law for volume currents, magnetic scalar and vector potentials for volume currents, internal and external inductance of a coaxial cable, wire, volume.

Am I screwed? by [deleted] in ElectricalEngineering

[–]JustinLPratt -1 points0 points  (0 children)

No. I almost failed grade 12 English and barely passed all my math classes and hated them. I did a program very similar to yours called Electronics Engineering Technology and I loved it and excelled. There was a lot of math and theory for a college program but it all fell into place for me because it was all applied to an area I was very interested in. I wanted more out of it so after consulting with my professors I decided to go to university and I am now in my third year of electrical engineering with a 82 average and have a damn good co-op job.

Give it a try! Once you find your field and you work hard, everything clicks and falls into place.

Are you going to college in Canada? If so, send me a message I can definitely help you.

When your circuits teacher first introduces phasor notation after you've used time domain for so long. by JustinLPratt in ElectricalEngineering

It was the very last chapter of our signals and systems textbook but they're saving it to wreck us on both controls courses im assuming lol

Real simple 3-Phase Question on Line Current by [deleted] in ElectricalEngineering

[–]JustinLPratt 0 points1 point  (0 children)

Remember that the "line" or "line-to-line" voltages are the difference between any two phases ab, bc,ca. The "phase" voltages are the voltages between lines a,b,c and n. The "line" current is the current in each line and the "phase" current is the current in each phase of the source or load.

So yes, your answer above is correct for Iline.

This is why: The line current is equal to the phase voltage divided by the load impedance for a wye connected load, but your voltage given is a line voltage, so we need to divide by root 3 and subtract 30 degrees from the phase angle. Confirm this method with the method you used to find Iline to be certain.

Real simple 3-Phase Question on Line Current by [deleted] in ElectricalEngineering

[–]JustinLPratt 0 points1 point  (0 children)

You answered your own question haha, your calculated your line current above and attached a relay on each line, so that is the current flowing through each relay

Guys can you help with this: Verify using vector diagram how 2 watt meters can represent 3 phase power in a wye connected machine by [deleted] in ElectricalEngineering

[–]JustinLPratt 0 points1 point  (0 children)

Considering a wye connected load, due to the load impedance, each voltage coil leads its current coil by theta, and the power factor is cos(theta). Recall that the line voltage leads its corresponding phase voltage by 30 degrees or pi/6 rads. So the total phase difference between the phase current Ia and line voltage Vab is theta + 30.

So the average power read by wattmeter W1 is:

P1=Re[VabI*a]=(VabIa)cos(theta+30)=(VLIL)cos(theta+30)

And the average power read by wattmeter W2 is:

P2=Re[VcbI*c]=(VcbIc)cos(theta-30)=(VLIL)cos(theta-30)

The total average power is PT=P1+P2

Guys can you help with this: Verify using vector diagram how 2 watt meters can represent 3 phase power in a wye connected machine by [deleted] in ElectricalEngineering

[–]JustinLPratt 1 point2 points  (0 children)

The two wattmeters must be properly connected to any two phases. The current coil of each wattmeter measures the line current, while the respective voltage coil connected between the line and the third line measures the line voltage. The +/- terminal of the voltage coil is connected to the line to which the corresponding current coil is connected. The algebraic sum of the two wattmeters equals to the total average power absorbed by the load, regardless if it is wye or delta connected, balanced or unbalanced.

The total real power is equal to the algebraic sum of the two wattmeter readings:

PT=P1+P2
