From the figure above. On the book I'm reading, KVL was applied from around the base-emitter circuit. (From Vee rotating clockwise.) The equation resulted to:
Vee + Ib*Rb + Vbe + IeRe = 0.
But looking at the placement of the battery, shouldn't it be: Vee - Ib*Rb - Vbe - IeRe = 0?
Note: The...
Problem : A 33 Ω half-watt resistor and a 330 Ω half-watt resistor are connected across a 12 V source. Which one(s) will overheat?
Choices: A.) 33 Ω B.) 330 Ω C.) Neither resistors D.) Both will overheat.
My solution: Since the phrase is "the resistors are connected across the voltage source...
Oh, so it's an extra given wherein I get to choose what formula to use. So, weight = (A)(length)(density).
Is the total loop length always twice the distance in a conductor?
I don't get it, I'm so sorry. From what I understand from the above, since case 1 and 2 uses the same material, density...
Problem: The resistance of the wire used for the telephone is 35 Ω per kilometer when the weight of the wire is 5 kg per kilometer. If the specific resistance of the material is 1.95 x 10^-8 Ω-m, (A) what is the cross-sectional area of the wire? (B) What will be the resistance of a loop to a...
Thanks to the both of you. The explanations are clear~ it somewhat irritates me when something simple yet hard or can't understand. :(
Thanks for that link, an additional knowledge for me.
Problem : Tank A contains a mixture of 10 gallons water and 5 gallons pure alcohol. Tank B has 12 gallons water and 3 gallons alcohol. How many gallons should be taken from each tank and combined in order to obtain an 8 gallon solution containing 25% alcohol by volume?
From the book, 2...
I got confused with analyzing circuits when it is assumed to be in ideal or practical model. On ideal model, they set the diode as a short component when it is in forward bias, so there will be no current flowing through the load resistor. But on practical model (where voltage drop is...
I am currently studying how Diode Clampers works. (Sorry for the newbie question.)
Regarding the picture above. On the result waveform after applying clampling / shifting techniques, I am wondering where did the -0.7 V on the graph came from?
On the negative alternation / half-cycle, the...
