Calculating Peak Current in an LRC Series Circuit

AI Thread Summary
To calculate the peak current in an LRC series circuit with given parameters, the relationship between peak voltage and peak current must be established. The relevant equations include V = IR and the differential equation -L dI/dT + Q/C = 0. The angular frequency, w, is determined using w = 2πf, where f is the frequency. The peak current can be derived by considering the impedance of the circuit, which combines resistance, inductance, and capacitance. Understanding these relationships is crucial for solving the problem effectively.

What's the relationship between peak current and peak voltage for an AC circuit?

(For a DC circuit you would use Ohm's law; what similar equation applies here?)

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 'Struggle to understand the concept of the 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...
