Electric circuits problem (RL/C circuits)

AI Thread Summary
To determine if an RL or RC circuit is a natural response or step response problem, one must consider the forcing function and initial conditions. The natural response occurs when there is no external voltage or current applied, while the step response involves an applied voltage or current at a specific time. Initial conditions, such as the charge on a capacitor or current in an inductor, play a crucial role in identifying the type of response. Resources like Absolute Astronomy provide additional insights into capacitors and inductors that can aid in understanding these concepts. Understanding these distinctions is essential for effectively solving RL and RC circuit problems.

when solving a RL or RC circuit, what's the easiest way to tell if it is a natural response problem or step response?
 
Physics news on Phys.org
What about the differential equation?

Are you asking about the difference between natural response and forced response? That depends on the forcing function.

See this page - http://www.absoluteastronomy.com/encyclopedia/c/ca/capacitor.htm , and

http://www.absoluteastronomy.com/encyclopedia/I/In/Inductor.htm

Or perhaps you are referring to the initial conditions - Initial potential or charge on a capacitor, or initial current in an inductor, which is then discharged, as opposed to no potential or charge on capacitor, or no initial current in an inductor, which then has a potential applied at some time, to.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
