I'm really glad I found your videos. I'm an undergraduate at a top tech university in Vietnam, but my lecturer teaches me in a very robotic way. For example, he expects me to remember methods to convert numbers in a robotic way, which contradicts my way of studying. Your videos help me understand the material deeply and are very easy to grasp. Thank you!

Hi, FYI, about 40 minutes in, the example (c) of the SPDT switch schematic has the switch arrow drawn incorrectly. Switching the arrow tip for lamp 2 will connect the 2 lamps and disconnect the voltage source. Not the same as example (d). The switch fulcrum (common) needs to be moved to the point labelled 1 for it to work correctly. Thanks for the lecture. It is a great reference for me after 33 years since my schooling. I'm instructing a protégé on basic electrical fundamentals and this is spot on good stuff and your delivery is pleasant to listen to. Your AC fundamentals course was really good too. Thanks.

when you do current division , you seems to use the denominator as only one branch of the parallel impedances, the denominator should be the sum of the parralel impedances
@profashleyevans
@profashleyevans Жыл бұрын
Hi Joe, thanks for watching! You might be thinking of a voltage divider here. When you have a voltage divider, the denominator is the sum of all resistances in series. But with the current divider, it is the numerator that is the total resistance of all the parallel paths you are dividing the current among. So in these problems, you'll see that the numerator is the combine resistance of all parallel paths, while the denominator is the resistance of the path in question, where the path we want the current for.

Why is current 3(I 3) in the second example flowing in a different direction? This is confusing me.
@profashleyevans
@profashleyevans Жыл бұрын
We can arbitrarily assign the direction of each current when beginning the problem. If the value for each current comes out positive, that means the direction we picked is correct. In this case, it might seem like the direction for I_3 should be reversed, at first glance. This current came out to be positive though, which means the polarity we initially selected is correct. Ultimately there is more current flowing from node A towards V2, than what is flowing out of V2 towards the node. So the final direction of the current is to the right.
@profashleyevans
@profashleyevans Жыл бұрын
Using superposition, you can determine that the current provided with only V1 in the circuit will be 652 mA, flowing from node A to V2. With only V2 in the circuit, 594 flows from V2 to Node A. This leads to a net current of 652 - 594 = 58 mA, flowing from Node A to V2. Therefore, the final direction of current I_3 is what is shown in the diagram. Does that make sense?

How do I calculate the voltage at B?
@profashleyevans
@profashleyevans 2 жыл бұрын
The voltage from terminal B to ground is the voltage across R2, which is also the voltage across X_L since they are in parallel. Since we have the current through I_C2, you can use that along with ohm's law to find the voltage across the parallel combination R2 // X_L, which would then be the voltage across each of those individual components.

How would you find Z1 using a calculator?
@profashleyevans
@profashleyevans 2 жыл бұрын
It depends on what kind of calculator you have. For example, a TI-89 can automatically convert from rectangular to polar and you can type in the entire calculation in one step. If you don't have an advanced calculator, you would need to do each calculation in multiple steps on your calculator. This might mean first converting from rectangular to polar, or polar to rectangular depending on what value you're trying to find, and then doing additional combination of rectangular values or polar values. I go over the conversion from rectangular to polar, and polar to rectangular in an earlier video within the AC circuits playlist. If you need to see that information, look for the introduction to AC circuits video I posted.

Hi there, by definition the ASCII code for any character is 7 bits. We will always add leading zeros to any representation that isn't naturally 7 bits. Then, we're adding a partity but to the front (for a total of 8 bits) just to provide an example of how parity bits might be used with an ASCII message. Does that make sense?

Hi Jon, thanks for the feedback! I'm glad you like the videos. I don't have any other videos with additional practice problems, but it's not hard to make up your own problems if you have a circuit design software such as multisim or pspice. You can use these programs to check your calculations. Or, grab a textbook similar to what we use in class, which is Principles of Electric Circuits, Conventional Current Version: Floyd, 10th Ed.
