Thread: circuit

i need help with this \;
how will anyone write a program for a circuit
like this :

[code]
|-------------------{Resistor}--------------|
| |
voltageSource| |Capacitor|
| |
|-----------------------------------------------|
using varous voltages;
such as v(t) = 12exp(t/RC)*sin((2*PI)/P);
P = period = 0 to 2.
wHO'S INTERESTING IN A CHALLENGE?
WHO IS WILLING TO TRY TO SOLVE THE SAME PROBLEM USING THIS.
TYPE | VOLTAGE SOURCE | DURATION APLIED(SEC)
1 | Vs = 12 | CASE 1;2
| | CASE 2; 0.4
_____|__________________________|_________________ _
| |
2 |Vs = v(t) = 12exp(t/RC)*sin((2*PI)/P | CASE 1; 2
| | CASE 2 ; 0.4
| | CASE 3; 2
_____ |_____________________________|_______________
3 |Vs = 12)*sin((2*PI)/P) | CASE 1; 2
| | CASE 2; 0.4
| | CASE 3; 2
_____ |_____________________________|_______________
4 | Vs = 0 t= 0 |
| Vs =12 0<=t>=0.2 | CASE 1;2
| Vs = 0 0.2<=t>= 0.4 | CASE 2; 0.4
| |
<------------------------------------------------------------------------------->


THIS HERE IS A TABLE(BELOW) WHICH YOU HAVE TO FOLLOW FOR EACH CASE.
HERE I HAVE R,C, t, P DEFINE IN THE TABLE BELOW FOR EACH CASE #

CASE| R | C | Vc (VOLTS) | P(SEC) | final (SEC)
1 | 0.3 | 1 | calculate | 2 | 2
2 | 0.05 | 1 | calculate | 0.03 | 0.4
3 | 0.3 | 1 | calculate | 0.03 | 2


this are your properties. who is up to the challenge?
who ever is teach how to! please!
I will appreciate.
tank you
HERE IS YOU HAVE TO FOLLOW THE PROPERTIES ABOVE

#include<theOracle> [U]CASE |

do you need the formula? your formula in C++ would be:

Code:

Vt = pow(12,(t/RC))*sin((2*3.14159/P);

you would need to have t,RC, and P defined before it goes into this equation, and it would give you V(t)...

what are you trying to find in that system? I couldn't really follow your forumula...

Not quite.

Code:

Vt = 12*pow(M_E,(t/RC))*sin((2*3.14159/P);

Don't forget to include cmath.h for the pow() function and the value of e, represented by M_E.

But I'm as confused as major_small : what are you trying to compute ? Voltage, current, ... ?

>>Don't forget to include cmath.h for the pow() function and the value of e, represented by M_E.

Acutally, its just #include <cmath>.

And yes, I do have that memorized.

Memorize this:

Code:

#include <cmath>
using namespace std;
.
.
.
cout << "PI:" << setprecision(50) << M_PI << endl;

>My memory isn't that good... and I only memorized that part of pi because I was bored in math.

>That was good tho :-)

Your memory is better than mine!!! I think me and the major tied.

i did have 3.1415926535 memorized at one point, but i forgot because of calculators... boredom does strange things to you sometimes...

I never knew that there was a constant defined for PI. Cool. I always just used 4 * atan( 1 ).

me neither... but i'll still be using the number... less steps...

Sorry, theOracle, even with your edit I have trouble understanding what you're looking for. Maybe the value of the RC constant ? Or the period ? Or maybe both ?

yeah, your edit didn't help that much... and include the closing [code] tag... the tags don't work if you only open it and never close them
