UL1 = L1L2i2+MU-M²i2
UL1-MU = L1L2i2-M²i2
UL1-MU = i2(L1L2-M²)
i2 = (UL1-MU)/(L1L2-M²)
am i right so far ?
now replace i2 in equation (1) with above? do i replace both i2 and i1 in equation 1 or just i2?
can end up with:
U = L1i1+M((UL1-MU)/(L1L2-M²))
or
U =...
I'm unsure do i need to try and rearrange U=L2i2+M((U-Mi2)/L1
for i2?
or the original simultaneous equation (2) for i2?...
U = L2i2+Mi1
U-Mi1 = L2i2+Mi1-(Mi1)
(U-Mi1)/L2 = (L2i2)/L2
(U-(Mi1)/L2 = i2
hi bit of further guidance on part c would be much appreciated.
so far following on from post #91
U=L2i2+M((U-(Mi2))/L1
i am unsure if I'm correct in how I'm going about rearranging for i2 here's what I've got so far.
i2= ((U-M)/L2) +M((U-M)/L1) ? i have a feeling its way out.
