How do you calculate the current of a transformer?


To calculate the current of a transformer requires one to compare the two coils' magnetic fields. Connect the power flowing through both coils. Concurring to the principle of conservation of energy, the power, or rate of energy transfer, has to be equal between the two coils. Syndicate these two equations to derive a third equation that directly relates coil turns with the voltage difference between circuits.

1. Equate the two coils' magnetic fields. Recall that a solenoid with current i and n turns has a magnetic field in the center of B=μin, where μ is the magnetic permeability
Measure the primary inductance with the secondary open. Then use 6.28FL (F= frequency, L=henries) to find the reactance in ohms (unless it's a tiny transformer the dc resistance can
For the experiment, it looks as though you were supposed to measure the current in either the primary or secondary, or else you you were to infer the current from a load of known
For all intents and purposes, none. Transformers pass alternating current. Now, if you want to split hairs, when a direct current is initially connected to a transformer, magnetic
