AC1 Fundamentals Unit 5 – Transformers
NEW TERMS AND WORDS
mutual inductance - the ability of one coil to induce voltage into another coil in close proximity
by way of a fluctuating magnetic field.
transformer - a device used to couple energy from one circuit to another through mutual
inductance.
primary - a transformer winding connected to the source voltage.
secondary - a transformer winding connected to the load.
coupling - the transfer of energy from one circuit to another.
tap - a fixed electrical connection to a specified position on the winding of a transformer.
autotransformer - a transformer consisting of one winding that acts as both primary and
secondary.
step-down transformer - a transformer whose applied primary voltage is greater than the
secondary voltage.
step-up transformer - a transformer whose secondary voltage is greater than the applied primary
voltage.
ferrite - a nonconductive, powered, compressed, magnetic, iron-based material.
