Hello,
I have been having a debate with someone that is driving me insane...
Here is the problem
http://www.ra31v1.pwp.blueyonder.co.uk/water1.JPG
Lets say we have 20,000m^3 of water like the image above.
If we were to freeze a quarter of it. what will happen to the level of the...
My god, after hours and hours of work trying to figure it out I've come to the conclusion that Xc = 1086 Ohms and R = 719 Ohms. in order to get the impedance 500 - j331. Not 100% sure if this is correct, but it seems to work..
All I need to do now is calculate what type of capacitor i'd need...
This is driving me crazy, I'm using the formula Z = R(XC squared)/(R Squared) + (Xc Squared) -j (R Squared)Xc/(R Squared) + (Xc Squared)
The first section being the real number and the second being the imaginary number. By using this I can figure out the parallel impedance of an RC...
Here is another problem that I'm not sure how to approach
A Circuit consisting of a 500 Ohm Resistor in series with a 1.2 micro F capacitor is connected to a supply at a frequency of 400Hz. Use complex numbers to determine the values of resistance R and capacitance C, that when connected in...
Okay, this is what I've done:
I got the inductive reactance using the formula 2piFL so XL = 30.16 Ohms.
I believe that the resistor being 20 Ohms would make the complex impedance Z = 20 - j30.16 because XL is negative on the phaser diagram.
Now, I find that converting both the complex...
Hi, here is the problem..
The potential difference across a circuit is represented by 40 + j25 volts, and the circuit consists of a coil with an inductance of 0.06H in series with a resistance of 20 Ohms. If the frequency is 80Hz find the complex number in rectangular form that represents the...
