LED States in Current and Reverse Bias Circuit

AI Thread Summary
In the discussion about the LED states in current and reverse bias circuits, it is established that LEDs 4, 5, and 6 are ON, while LEDs 2 and 3 are OFF due to high resistance in reverse bias. The question arises regarding LED 1, which is connected in series with LEDs 2 and 3, and whether current can flow through it despite the reverse bias affecting the others. The clarification provided indicates that current cannot flow through LED 1 when LEDs 2 and 3 are OFF. Ultimately, the understanding is that all series-connected LEDs must conduct for current to flow, confirming that LED 1 is also OFF.

Homework Statement


Indicate which of the 6 LEDs are ON and which are OFF


Homework Equations


V=IR


The Attempt at a Solution


Okay, I know LEDs 4,5 and 6 will be ON and LED 2 and 3 will be OFF but what about LED 1? Because LED 2 has a very high resistance as it is reverse biased thus no current flows, but would that mean current would still flow through LED 1?

LED-s 1, 2, 3 are connected in series. Can the current flowing through LED 1 be different from the current which flows through the other ones?

oh i See! thankyou I understand now.
 

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...
