I used this website to try and help me to reach my answer: http://epb.apogee.net/foe/fcspp.asp it seems like adding more in parallel shouldn't change how bright the other parallel ones are? I'm confused why B should change.

Homework Statement 2 different questions that I'm using to test my understanding of the physics concepts rather than the math: 1) How does the brightness of bulb A compare to that of bulb C? After D is added how does the brightness of bulb A change? Does the brightness of B change? Does...

Homework Statement Not sure if I'm doing this problem correctly (no answer key for these practice problems). I just want to check with people that know this material well enough. A hollow spherical non-conducting shell of inner radius a and outer radius b carries charge density p = C/r^2 in...

Consider a total charge of q = 3.50 10^-9 C spread uniformly over a thin rod of length L = 0.8 m as shown. Point P is a distance H = 0.6 m away from the midpoint of the rod. Find the magnitude of the electric field at point P. Relevant equations: E = k \int \lambda dx/r^2 where \lambda =...
