Oh I never thought of that okay thanks a lot!

If I take 1/N of the total current and say that that is going through the first bulb is that not assuming that the current is evenly distributed to all the loads. whenever I have done questions where the current splits into two directions it hasn't been an even distribution of the current?

Homework Statement Okay, so there is a battery with in internal resistance r and voltage of (V). The battery is hooked up to an infinite number (N) of lightbulbs each with resistance R in parallel. The question asks me to find the current going through the first lightbulb...My problem is when...

ya that's my fault i was re-writing the question to make it shorter thank you for the help!

Homework Statement A 5.5kg box is attached to a spring which is attached to a wall. The box is subject to a force of 90N moving it from its equilibrium to a position 40cm away, the coefficient of kinetic friction is 0.300. a. what is the work done by the applied force over the 40 cm? b.what...

Thankyouuuu! :approve::smile::biggrin:

ohhh.. is it inside the wire I would only use the current component of the inner wire, between the two I would still only use the inner wire, and then outside i would add the two to get Ithrough=0?

Thanks, so if I model the outer tube using Ampere's Law to calculate the Ithrough wouldn't that give zero current and then zero magnetic field?

Homework Statement So I'm doing a problem set and the question refers to a coaxial cable, I am told that the cable consists of an inner solid cable radius (R1), which is surrounded by a outer thin tube with radius (R2) , both have the same current though them but opposite direction. I have to...
