    Current Switch
AI Thread Summary
The discussion centers on calculating the current flowing through an on/off switch in a circuit powered by a 20-volt battery. Participants are trying to determine the correct answer from multiple-choice options, with one user initially estimating a current of 0.38 amperes. Another user encourages showing the calculation process to verify the answer. The calculation involves combining resistances and applying Ohm's Law, leading to a confirmed current of 0.38 amperes. Accurate calculations are emphasized for clarity and correctness in electrical assessments.

What current is flowing through the on/off switch?

The circuit below is powered by a 20-volt battery. What current is flowing through the on/off switch (When it is on, as shown)?

A. 0.23 amperes
B. 0.29 amperes
C. 0.32 amperes
D. 0.38 amperes


i tried myself i got a close answer to D. 0.38 amperes but i want to make sure thanks you! ☺

Would you like to show how you got that?

No, we want you to show your work.
 


1/16 + 1/20 = 0.1125

1/0.1125 + 24 +20 = 52.8

20v/52.8 = 0.38
 


Looks good! :smile:
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

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 hanging mass'

Thread 'A cylinder connected to a hanging 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...
