Finding current across capacitor
Homework Statement An ac generator with a frequency of 30.0Hz and an rms voltage of 12.0V is connected to a 45.5uF capacitor. a) what is the maximum current in this circuit? b) what is the current in the circuit when the voltage across the capacitor is 5.25V and increasing? c) what is the...- kayak4life87

Solenoid length of wire problem
aaahhh.. i got it now.. i was not even thinking when that was the length of solenoid. I found the number of turns and then used the circumference of the cylinder.. Thanks everyone for your help. thanks again.- kayak4life87

Solenoid length of wire problem
ya i converted the 2.5kG to Tesla 1kG=1000Gauss 1Gauss=.0001 tesla You are given B, I, uo, L=55cm, diameter=12cm, B=2.5kG=0.25T I first used the equation B=uo(n)I and solved for n, then used n=N/L to solve for N then once you have N I put that back into B=uo(N/L)I. But of course I am...- kayak4life87

Solenoid length of wire problem
well i have used the B=uo(N/L)I n=N/L I tried solving for n and then plug that into the second equation there and solving for N. Then once you have N put that into the first equation and solve for L. However, this is not working and I don't really know another approach unless I am doing...- kayak4life87

Solenoid length of wire problem
Hey so I have been trying this problem and just cannot get it. thanks for the help. To construct a solenoid, you wrap insulated wire uniformly around a plastic tube 12cm in diameter and 55cm in length. You would like a 2.0A current to produce 2.5kG magnetic field inside your solenoid. What...- kayak4life87
