AI Thread Summary
When switch 1 is closed, current flows from the positive terminal through a coil, generating a magnetic field. This magnetic field activates the second circuit, causing its switch to close. However, the response is not instantaneous; there is a slight delay in the operation. The sequence accurately describes the functioning of an electromagnetic relay. Understanding this process is crucial for grasping the principles of electromagnetic devices.

Electromagnetic relay(check my solution please :) )

Homework Statement


The following diagram shows an electric device that uses some of the principles discussed in this lesson.

Discuss the sequence of events that occur when switch 1 is closed.

*The diagram is in the attachment, you don't have to download the attachment to view it *

Homework Equations


The Attempt at a Solution



Current flows through the circuit, coming out of the positive terminal in circuit 1, hitting the metal which is wrapped around a coil, this would create a strong magnetic field , which would then act upon the 2nd circuit. This then immediately closes the 2nd switch, the current in the 2nd circuit can then flow.
Is this what happens? If not can someone please tell me what happens then?

Yes, but not instantly :wink:
 


Ahh.. thank you! :)
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
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}...
