No thanks for asking the questions, it made me think.
I've run into another issue. I'm reading my textbook, which says:
"Although tungsten is an effective filament, when it is hot the tungsten vaporizes and the filament becomes thinner. This increases its resistance, which means it shines...
I wasn't exactly sure what you meant in your question.
If i had to describe the bulb to you, and by pick up you mean go and get an identical bulb, i guess i would say "get me a 30 watt bulb"
Why does less current mean anything?
If there's less current, it means there's less power...
I think the bulbs will be dimmer because more resistance equals less current. The thing that confuses me is that if the resistance is raised in one of the bulbs, it will shine brighter. To me that goes against the more resistance = less current explanation. If the resistance in a bulb is raised...
Hello!
So i have a series circuit, say just 1.5v and i already have a bulb glowing. Let's say i add a bulb of similar resistance. I know the current will decrease because the overall resistance of of the circuit increases.
But do the bulbs both shine as bright as they did before? Or less...
