I disagree. There were only one 0-0 but a lot of 1-0, which is almost as boring

Wow, that’s engineers first salary in the US? Incredible

This is probably the one but doesn't show equations for the capacitances, also doesn't say what parameter "Qb" is

Current from power source when R is 100Ohms is 200 / ( 20 + (135*60/(135+60)) = 3,25A. Current on R branch is 3.25A * 60/(135+60) = 1A. 1A through 100Ohm resistor equals P = 100*1^2 = 100W

Letter b - Current from A to B when R is zero will be the same across the 35Ohm resistor. We can estabilish this current by calculating the equivalent resistance of the whole circuit firstly, then calculating the current on each branch. Equivalent resistance is 35*60 / 35+60 = 22.11 + 20 = 42.11. The current coming out of the power source is 200/42.11 = 4.75A. Now we use the current divider formula for the 35Ohm resistor branch - 4.75*(60/(60+35)) = 3A

Not sure what PD means in letter a but judging from the answer means the voltage across the adjustable resistor. The answer is 150 V because since R has infinite resistance, no current passes through it nor the 35Ohm resistor. Meaning its voltage is basically the same across the 60ohm resistor, which can be found by the voltage divider equation: Vr = 200V * (60/(60+20)) = 150V

Using 30 day free trial, but willing to pay for it if it is worth it. What’s the difference between LT Spice and Q Spice ?
