The Practical Transformer G006A

1. Silicon steel is used in the construction of transformer cores as it reduces the ________________________ loss.

• eddy current

• flux

• hysteresis loss

• induction

1. The core of a transformer is laminated to reduce the _______________________ loss.

• flux

• coil

• eddy currents

• capacitance

1. Joints in the laminations of a transformer core are staggered to reduce the ______________________ of the core.

• resistance

• reluctance

• reactance

• flux

1. In a concentric type winding the ___________________ winding is usually placed closest to the transformer core.

• primary

• low voltage/tension

• secondary

• ratio

1. In a transformer, sections of both primary and secondary windings are usually wound on each limb to reduce -

• magnetic leakage

• iron losses

• hysteresis losses

• the amount of wire

Transformer laminations are tightly clamped to reduce

• flux

• losses

• noise

• mutual induction
