Which of the following are the three types of electrical loads?

The classification of electrical loads as resistive, inductive, and capacitive is fundamental in understanding how different types of loads behave in an electrical circuit.

Resistive loads are those that predominantly convert electrical energy into heat, such as heaters and incandescent light bulbs. These loads operate on the principle of resistance, where the current and voltage are in phase, meaning that the current reaches its maximum value at the same time as the voltage does.

Inductive loads, such as motors and transformers, store energy in a magnetic field when current flows through them. In these cases, the current lags behind the voltage in phase, which can affect the overall power factor in a circuit. This distinction is crucial for electrical engineers and apprentices to grasp when working with various types of machinery and devices.

Capacitive loads, including capacitors and some forms of power factor correction devices, store energy in an electric field. For capacitive loads, the current leads the voltage in phase. Understanding these three load types is essential for designing and troubleshooting electrical systems effectively, as they influence how energy is distributed and utilized within circuits.

The other options represent different classifications of electrical concepts. For instance, active, reactive, and apparent power describe the different forms of power in AC circuits,
