Hi guys,
So I'm starting to learn about magnetic fields and electrics fields, one of the equations we use is v= -L*di/dt ... I've been trying to figure out how it's derived, in my book it says:
it starts off like this:
1. v=-dθ/dt (faraday's law) <- why is there no N(no. of turns) in this equation?
2. L = θ/i therefore θ = Li
3. putting them together gives v=-L*di/dt
so my question is, why did the course book not use v= -N*dθ/dt ?
thanks again guys
