    Heat Resistors
AI Thread Summary
Heat affects resistors by increasing their resistance due to the temperature coefficient of the material, which can lead to changes in voltage across the resistor in a circuit. According to Ohm's Law, as resistance increases with temperature, the current flowing through the circuit decreases if the voltage remains constant. This relationship is crucial for experiments where precise control of resistance and voltage is necessary. Managing heat is essential to ensure accurate results and prevent component damage. Understanding these principles is vital for effective circuit design and experimentation.

I'm doing coursework and i know it's dumb but i just can't remember how heat is supposed to affect resistors *heh* If someone could give me a quick explanation, it's not for the main part of the coursework, it's just a factor i have to controll in another experiment, but i can't remember why i have to controll it!

thanks, one more question, why would that affect the voltage in a circuit with a resistor?

Think about Ohms Law.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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}...
