Incorrect??phinds said:
well, what do you mean by it? What it says to me is very literal, A equals B and either both are greater than C or at least B is greater than C. I don't see how you get that from what's going on. Do you mean something else?kamhogo said:
I mean that A and B are equally bright and that both are brighter than Cphinds said:
Yes, that's what I thought. Is that really what's happening?kamhogo said:
Sorry, I was confused. I meant A=C>B. Also, is there any current passing through B at all?phinds said:
Yes, that makes sense.kamhogo said:
what do you think?
I think there's no current passing through B at all. My reasoning: why would the electrons go through path with a resistor that does not lead to the negative terminal of the battery when they have the choice to take a resistless (ideally) path that leads to the negative terminal of the battery.phinds said:

I don't understand this. Can you explain?
Your answer is correct. Have you studied what an "open circuit" is?kamhogo said:
Not yet, but I am curious. I'll look it up. Is it when there is a gap somewhere on the circuit so the current pass? What is it useful for?cnh1995 said:
It is the technical term for a "gap" in the circuit, so current can't flow through it.kamhogo said:
The best way to determine which identical bulbs are the brightest is by measuring their luminosity or brightness using a light meter. This will give you an accurate numerical value for each bulb's brightness, allowing you to rank them accordingly.
No, wattage and voltage are not reliable indicators of a bulb's brightness. These measurements only indicate the amount of energy a bulb consumes, not how bright it will be. Bulbs with the same wattage or voltage can have different levels of brightness.
Yes, there are other factors that can affect a bulb's brightness, such as the type of bulb (incandescent, LED, etc.), the color temperature, and the age of the bulb. These factors can impact the perceived brightness of a bulb even if they are identical in terms of luminosity.
Yes, you can use the same measurement of luminosity to compare the brightness of different types of bulbs. This is because luminosity is a standardized unit of measurement that takes into account the human eye's sensitivity to different wavelengths of light.
If you are comparing the brightness of identical bulbs, it is important to keep them in the same position and direction to ensure accurate results. This is because the brightness of light can vary depending on the angle and distance from the light source. To minimize these differences, make sure the bulbs are placed and facing the same direction when measuring their brightness.
