    Current Resistance
AI Thread Summary
A user seeks help with understanding how a computer joystick operates in relation to current and resistance for a homework assignment. The discussion highlights the role of two orthogonal potentiometers in detecting the joystick's angular position. It emphasizes that moving the joystick alters the position of the potentiometers' wipers, which affects the circuit's resistance and current flow. Understanding this interaction is crucial for explaining joystick functionality. The conversation aims to clarify these concepts for the user’s assignment.

I am very new to this forum. Please excuse my ignorance.

I have a packet due tomorrow and I need immediate help on this problem. I somewhat understand electric circuits but this packet continues to irritate me.

anyhow, the first page of the packet has this (see attachment) picture. And the question simply states explain how a computer joystick can be sued to maneuver around the screen (discuss both current and resistance in your explanation)

Please HELP!

Welcome to the PF. The pic shows two orthogonal potentiometers. How would you use the two variable resisances to indicate the angular position of the joystick?

I don't know, how would you?

What do you think moving the joystick does to the postion of the potentiometers' wipers?

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}...
