Battery’s terminal potential difference

AI Thread Summary
The discussion focuses on calculating the terminal potential difference of a 1.5 V AA battery connected to a circuit with a total series resistance of 50 ohms and an internal resistance of 1 ohm. The user correctly applies the formula I = EMF / (R + r) to find the current, resulting in 29.412 mA. They then calculate the terminal voltage as 1.47 V by subtracting the voltage drop across the internal resistance from the EMF. The method used is confirmed as correct, and an alternative approach using the potential divider rule is suggested. Overall, the calculations and methodology are validated by other participants in the discussion.

Homework Statement


An external circuit with a total series resistance of 50 (omega) is connected to a 1.5 V AA battery which has an internal resistance of 1 (omega). What is the battery’s terminal potential difference?

Homework Equations


I = EMF / (R + r)

The Attempt at a Solution


I = EMF / (R + r) = 1.5V/ 51 Ohm = 29.412 mA

V = 1.5V - 0.029412A * 1 Ohm = 1.47 Voltbut i m still confused if i did it right or wrong please help

Thank you!

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
