When hearing "Hi, I'm Dr. Kyle Montgomery." became a weekly routine... Dr. Montgomery, I don't know if you will check the comment, but I just want to say that after the whole spring quarter, I really look up to you as a role model (with your attitude toward things, your music and of course your teaching). Wish you all the best with your new job, Dr. Montgomery!!

Did you write mirrored in the whole video? :O
@KushMcDee7 жыл бұрын
No, he's not writing it mirrored. You can tell that the recording is simply flipped horizontally because the text on his shirt is backwards. If this helps to picture it: before they flipped the image horizontally, everything facing us actually was backwards and he was writing it normally on his side.

I've done this one multiple times and looked it over and over and over. I am not getting the same results....is the set up wrong at all?

i tought the formula with relation to the voltage and number of turns was E1/E2 =N1/N2

due to subtractive polarity, the negative sign is preceded.

Can ask you how to you decide the voltages v1 and v2 signs and the currents direction does it work however you choose them

equation 2 should be i2=4i1
@suhailasami28448 жыл бұрын
hi, for equation 2, isn't it supposed to be negative 4I_2 rather than positive? or no?
@dhrupadsaha41714 жыл бұрын
nope. current is entering at one dot terminal while leaving the other dot terminal at the other side. so the sign convention taken is ok

Isnt V1 / V2 supposed to be equal to I2/ I1

Couldn't you just use Z on the primary side = (Z on the secondary side/n^2) Where n is N1/N2?

i thought the dot is where the positive terminal of the inductor in the second loop

About the dots: The dots are used to take into account the spatial orientation of a winding with respect to the other winding. If we didn't use the dots, we'd have to draw how each winding is wound around the core; this would be tedious, so instead we use the dot convention. About the positive voltage: When you draw the "+" and "-" polarities of a voltage, it means that a positive voltage (v > 0) would mean the "+" node has a higher potential with respect to the "-" node; a negative voltage for the same polarity (v < 0) would mean the "+" node has a lower potential with respect to the "-" node. Remember that when you're going to solve a circuit, you first must _assume_ a direction for the currents and a polarity for the voltages; this is where the terms _reference direction of current_ and _reference polarity of voltage_ become useful. After you solve the circuit, you can determine the actual polarity of voltages and direction of current. A voltage value on its own (for example "8 V") has no physical meaning unless you say which two nodes you're comparing their potentials; this is because voltage is a potential _difference,_ and a difference requires to compare two values (for example, when you say the height of a mountain is X meters, it actually means the diestance above the sea level to the top of the mountain; when you talk about temperature or pressure you're also comparing.)
