When in series, the total inductors value is added together.
|
||||
|
||||
When in parallel, the total inductance is equal to the reciprical of the sum of
|
||||
recipricals. This means that for three inductors L1 L2 and L3, the total
|
||||
inductance of them in parallel is
|
||||
|
||||
Total = 1/(1/L1 + 1/L2 + 1/L3)

|

Transformers are an application of mutual inducatance, caused by inductors.
|
||||
Transformers transfer power between two inductors that share a mutual core.
|
||||
Two sets of windings (giving winding is primary, pulling winding is secondary)
|
||||
are used and rated in the given direction, however it works both ways.
|
||||
|
||||
By using different amounts of windings on each side we can step up or down
|
||||
voltage and current. This is because the same amount of energy is on both
|
||||
sides, however if there are fewer turns then the energy is more concentrated,
|
||||
leading to a step up transformer.
|
||||
|
||||
The relationship between input and output voltages are based upon the primary
|
||||
winding N,,p,, to the number of turns on the secondary winding N,,s,,. The
|
||||
relationship with their voltages _E_ is shown below
|
||||
|
||||
E,,s,, / E,,p,, = N,,s,, / N,,p,,
|
||||
|
||||
E,,s,, = E,,p,, * N,,s,, / N,,p,,
|
||||
|
||||
Example,
|
||||
|
||||
What is the voltage across a 500 turn secondary if 120V is across a 2250 turn
|
||||
primary?
|
||||
|
||||
120V * 500 / 2250
