Types of loads and Phasor Diagrams:
Pure Inductor load:
- The load which contains only inductance (L) and not any other quantities like resistance and capacitance in the circuit is called a Pure inductive load.
- In this type of load, the current lags behind the voltage by an angle of 90 degrees.
Pure capacitor:
- The load which contains only capacitance (C) and not any other quantities like resistance and inductance in the circuit is called a Pure capacitive load.
- In this type of load, the current leads the voltage by an angle of 90 degrees.
RL load:
- The load which contains only Resistance (R) and Inductance (L) and not any other quantities like capacitance in the circuit is called a RL load.
- In this type of load, the current lags behind the voltage by an angle between 0 to 90 degrees.
RLC Load:
- When a pure resistance of R ohms, a pure inductance of L Henry, and a pure capacitance of C farads are connected together in series combination with each other then RLC Seriesload is formed.
- As all the three elements are connected in series so, the current flowing through each element of the load will be the same as the total current I flowing in the load.
Case I
RLC load with inductive reactance more than the capacitive reactance
Where
VL = Inductor voltage
VC = Capacitor voltage
I = Current
V = Supply voltage
VR = Resistor Voltage
Case II
RLC load with inductive reactance lesser than the capacitive reactance
So If we observe the phasor diagram between V and I in all cases, RL load or RLC with inductive reactance more than the capacitive reactance (Case II) matches the given phasor.
