- Mutual inductance: This is when the magnetic flux of two or more inductors are linked up together in that the voltage induced in one coil is proportional to the Chang of current in the another.
- Coefficient of coupling: This is the magnetic flux produce by current in one coil which links with the other coil.
B) 500/200v single phase transformer has primary resistance of 0.5Ω and reactance of 3.7Ω, while the secondary resistance and reactance are 0.03Ω and 0.25Ω respectively. Compute the equivalent values of resistance, reactance and impedance referred to the primary and secondary
