Hmmmm... in school, we learned that the magnetic field in a solenoid is modeled by the following equation
B= πο In/L,
where u is equal to 4 π (pi)* 10 to the power of -7
I is equal to current
n ο (sorry, don't know how to do subscripts) is equal to number of loops
and L is equal to the...

I'm having trouble find the total resistance of circuits with cells in parallel. The answer in the book is 31 ohms, but my calcuation ends up as 30 ohms. What am I doing wrong? (Please show steps if not too much trouble) Thanks in advance!:D
See this site for my work and a diagram of the...
