Why is the speed of sound always the same in the same medium?
Shouldn't the wave move faster if more pressure is generated?
Suzuki GSX-S 125, gearshift?
Hello, I bought a new motorcycle, the Suzuki GSX S 125. My question is: At what speed do I need to shift into a higher gear? Of course, you should be able to hear it. But if anyone happens to have a motorcycle like that, they could help me, since I can't really hear it….
Can you use a loose socket?
Bykukury
Hello, I have a question for you, and it's about the socket. I would like to charge my laptop, but the socket is loose, so it moves and is not very stable. But can I still use it, or is it dangerous?
What resistance is this?
Hello, a capacitor on my television has burst and destroyed a resistor. What is the resistance value of the resistor shown in the photo? If I see it correctly, the colors on the resistor are red, yellow, silver, and brown. Thank you very much for your help.
Turned on the light switch with a wet hand?
ByDrago562
Hello, I just turned on a light switch with relatively wet hands. I deliberately touched the middle so that I wouldn't touch the edges with my wet hands. Is that dangerous in any way? The current doesn't just jump over.
Unscrewing the Blu-ray player – risk of electric shock?
ByRebe95Lu
Good evening, I have an old Blu-ray player from 2009. It's stopped working and won't start anymore. Unfortunately, I can't get my DVDs out either. Now I'd like to open it. What did make me a little suspicious is the warning that it shouldn't be opened due to the risk of electric shock. But that…
In a branch I is always the same. I is not consumed.
I2=I3 and I4 = I5
Since both branches are identical, I2 =I3 =I4 =I5.
The current must be supplied by the power source and flows back there.
I1 = I2 + I4 = I6
It says: The incandescent lamps have the same design, i.e. the same resistance.
This results in:
I2=I4 (because everything is the same)
I1 = I2 + I4 (because the sum of 2 and 4 is yes 1)
and I1 = I6; I1 = 2 * I2 etc. If one considers the current direction to be irrelevant, since no directional arrows are indicated there
