Difference Between Inductive Load and Capacitive Load
(1) The main difference between Inductive Load and Capacitive load is, that inductive load causes to lag in the current behind the voltage whereas capacitive load causes to lead the current behind the voltage. According to the nature of the load, there are three types of load - 1. Resistive Load 2. Inductive Load 3. Capacitive Load. Let's see the other differences between Capacitive Load and Inductive Load
(2) The main function of an inductive load is to convert electrical energy into magnetic energy. Generally, it produces a magnetic field when connected to a power supply. On the other hand, the main function of capacitive load is to store the electrical energy or return the electrical energy to the power circuit after consumption. So, the capacitive load does not consume power, if consumed, again it returns to the circuit.
(3) Inductive loads have inductive coils made by electrical conductors. So, they also offered electrical resistance against the power supply due to the internal resistance of the wire of the coil. On the other hand, the capacitive load does not offer resistance like inductive loads, they have very low internal resistance compared to inductive loads.
(4) The inductive load can cause electrical power loss(copper loss or iron loss) due to their internal resistance, wasting of magnetic flux, etc but the capacitive load does not cause so much electrical power loss due to their internal construction.
(5) Inductive load causes to make lagging power factor whereas the capacitive load causes to make leading power factor. For example, an electric motor such as an induction motor is the inductive load. When it is connected to the power supply, it consumes both active and reactive power. It causes the consuming current to lag behind the supply voltage. So it causes the power factor lagging. On the other hand, a Synchronous Motor is a capacitive load that causes to leads the current behind the supply voltage. So, it causes the power factor leading.
(6) Most of the inductive loads such as electric motors, and actuators are heavy in nature, which means they consume a large amount of current. On the other hand, most of the capacitive loads are lighter in nature. Mainly they are used for protection, controlling, power factor improvement, and reactive power compensating purposes.
(7) Inductive load can improve the power factor by compensating for the leading power factor whereas capacitive load can improve the power factor by compensating for the lagging power factor.
(8) Inductive loads can generate heat due to power loss in their internal resistance whereas capacitive loads also generate heat but very low compared to inductive loads.
