How do you know if a circuit is resistive inductive or capacitive?
How do you know if a circuit is resistive inductive or capacitive?
If both inductors and capacitors are present then simply find the equivalent impedance of the load network. 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 do you know if a RLC circuit is capacitive or inductive?
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 a purely resistive circuit?
A purely resistive circuit is a circuit that has inductance so small that at its typical frequency, its reactance is insignificant as compared to its resistance. Furthermore, in a purely resistive circuit, the whole of the utilized voltage is consumed in overcoming the ohmic resistance of the circuit itself.
What is a purely inductive circuit?
A Pure inductive circuit is one in which the only quantity in the circuit is inductance (L), with no other components such as resistance or capacitance. The current in this type of circuit lags behind the voltage by 90 degrees.
What is resistive impedance?
RESISTANCE. IMPEDANCE. Definition. The opposition offered to the flow of current in an electric circuit is known as the Resistance. The opposition offered to the flow of current in an AC circuit because of resistance, capacitance and inductance is known as Impedance.
Which is true about purely inductive circuit?
The pure inductor does not consume any actual power from source. Apparent power of the circuit is zero. A pure inductor has 90° power angle between voltage and current. Hence, cos90° is zero and thereby the actual power P = VIcos90° is also equal to zero.
