How do you tell if an RLC circuit is inductive or capacitive?
If the inductive reactance is greater than the capacitive reactance i.e XL > XC, then the RLC circuit has lagging phase angle and if the capacitive reactance is greater than the inductive reactance i.e XC > XL then, the RLC circuit have leading phase angle and if both inductive and capacitive are same i.e XL = XC then …
What is inductive and capacitive load?
Compared to resistive loads, inductive load current peaks after voltage. Consequently, inductive coils produce lagging power factors. Capacitive load elements use capacitors that store electrical charge. They resist changes in voltage, which causes current to peak before voltage during each electrical cycle.
What is the example of inductive load?
Reactive/Inductive Load – An inductive load converts current into a magnetic field. Inductive reactance resists the change to current, causing the circuit current to lag voltage. Examples of devices producing reactive/inductive loads include motors, transformers and chokes.
How is a capacitive load different from an inductive load?
While a capacitive load is reverse of an inductive load. It resist changes in its voltage i.e voltage across a capacitor can not be changed instantaneously. So in this case voltage lags behind current.
How to calculate the impedance of a load?
If the imaginary part of the equivalent impedance is positive then the load is inductive, if it is negative then it is capacitive, and if it is zero then it is resistive.
How to know if the circuit is purely resistive, inductive or capacitive?
A purely resistive circuit will have no difference in the phases. A purely inductive circuit will have the current lagging from the voltage by a quarter of a full period. A purely capacitive circuit will have the current leading the voltage by a quarter of a full period.
Are there any problems with a capacitive load?
In an electronic system with a capacitive load there may well be further problems. For example, a BJT common-collector output stage with a capacitive load is slew-rate limited if it tries to reduce output more quickly than the resistive load can discharge the capacitance. The capacitance can keep the em
