Load Evaluation

Electrical Loads are electronic elements of a circuit that exhausts electric power. Examples are appliances and bulbs. Load evaluation is a structured calculation or deduction that shows the general power rating chart of regular electrical devices in watts. Electricity loads are measured in Watts, a unit of power.

The three types of loads in circuits are: capacitive loads, inductive loads and resistive loads. Capacitive load is simply referred to as a capacitor. A capacitor is a part of electronic equipment that allows the flow of alternating current without passing a direct current. It is always used in an electronic circuit. Therefore, capacitive loads cause voltage waves.

Inductive loads convert current into a magnetic field. Examples include fan, electric motor, air conditioner etc.

Resistive Loads are electric devices that are composed of heating elements which do not influence electric current or voltage. Examples include: lights, ovens, electric iron, kettles etc.

Battery recommendation and energy consumed by appliances are to be put into consideration when you want to do load evaluation. Batteries may be wired in either series or parallel connection. In series connection, the positive end is corded to the negative end of another battery. Here, the voltage is added together, while the current stays the same.

Parallel connection is done by wiring the positive end of a battery to another battery’s positive end, and negative to the next negative. This connection increases amperage while maintaining voltage. In some instances, you can have a parallel and series connection.
