Resistive and Inductive Loads
Resistive loads typically convert energy into heat during the electrical process. The heat must be expelled from the system through a medium such as air or water, and the energy can be utilized purposely in heating devices. To achieve high efficiency, it is essential to optimize the voltage use of a resistive load. When a resistive load operates under the proper voltage, it ensures a constant supply of energy and protection from loss of energy to sensitive devices.
An inductive load is a part of an electrical circuit that uses magnetic energy to produce work. Some common examples include transformers, electric motors, wound control gear and electromechanical relays. These sorts of tools basically store energy until it is needed and, once it is, they convert it with a series of magnetic fields. And these sorts of loads often have to be harnessed and protected to keep the energy flowing in only one direction, since the force of the power can cause damage to the circuit or connected breakers otherwise.
