Definitions:

Resistive Load

An electrical load that consumes energy in the form of heat or light, behaving according to Ohm's law.

Turns Ratio

The ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer, affecting its voltage and current transformation.

Primary Leads

The main electrical conductors or connections that provide a path for electrical current to enter or exit a device or system.

Secondary Leads

Wires or conductors that connect the secondary winding of a transformer to the load or output, transferring the transformed voltage or current.
