Durrr i'm returded

[vespertine]

im onto slope fields right now. i need insight into how slope fields can be used for physical situations as well. this next section is confusing me because of the quantity of variables and terms:

suppose a simple electric circuit contains an electromotive force (usually a battery or generator) that produces a voltage of E(t) volts (V) and a current of I(t) amperes (A) at time t. The circuit also contains a resistor with a resistance of R ohms (Ω) and an inductor with an inductance of L henries (H).

Ohm’s Law gives the drop in voltage due to the resistor as RI. The voltage drop due to the inductor is L((dI)/(dt)). One of Kirchhoff’s laws says that the sum of the voltage drops is equal to the supplied voltage E(t). Thus we have

L((dI)/(dt))+RI=E(t)

which is a first-order differential equation that models the current I at time t.

before we bring slope fields into this, what does all this shit mean? i feel so stupid

interesting. so you're saying that according to Kirchhoff’s Voltage Law, if you go around a closed loop in the circuit, the sum of the voltage rises and drops must equal zero (energy is conserved)?

my head is torturing me impossible to read

 

[vespertine]

This equation describes how the current I(t) changes over time in response to the battery voltage E(t).


Basically, it says:

The rate of change of the current (how fast it’s increasing or decreasing) depends on how strong the supply voltage is, and how much resistance and inductance oppose it.

alright, this clears things up. thanks

 

[lolfask]

alright, this clears things up. thanks

np i am a nice fellow

 

[vespertine]

when i was younger, i was molested by a guy with down syndrome

??

 

[Xoogster]

Hi retarded, I'm Dad.

 

[Xoogster]

Didnt like my joke bitch?

 

[cut]

what are you confused about

 

[lemonpie]

Stop Calling yourtself a SLur!!! DOnt do that!!!!!

 

[lemonpie]

what are you confused about

Fellow MLPbrony!!!!!! Heck yeah!!!!!!!

 

[vespertine]

Didnt like my joke bitch?

r**e xoogster day is next monday

 

[vespertine]

what are you confused about

my love

my love

are you confused about the leibniz

 

[vespertine]

are you confused about the leibniz

im basically black when it comes to math, i don't know a thing.

L((dI)/(dt))+RI=E(t)

dI/dt -> derivative of I with respect to t (how fast the current is changing over time = amps/second for example)
(e.g derivative of distance with respect to time is dx/dt -> how fast distance [metres] are changing over time = metres/second = speed)
