7 Questions
What is the complex impedance of a two-terminal network expressed as?
Z = r + jx in Cartesian form, and Z = zeiФ in polar form.
What is the phase angle of the voltage across the capacitor and inductor in a series RLC circuit?
180°. The voltage across the capacitor lags the current by 90°, and the voltage across the inductor leads the current by 90°.
What is the condition for the circuit to be resistive in a series RLC circuit?
XL = XC.
What is the formula for the impedance of a series RLC circuit?
Z = R + jXL - jXC.
What is the phase angle Ф of the circuit in a series RLC circuit?
Ф = tan-1((XL - XC) / R).
What is the significance of the voltage across the capacitor and inductor being equal in magnitude?
They cancel each other, and the total reactance in the circuit is zero.
What can be concluded if XL > XC in a series RLC circuit?
The circuit is inductive.
This quiz is about the experiment to study the AC characteristics of RLC circuits, covering the apparatus and theory behind it. Topics include impedance, complex voltage and current, and Cartesian and polar forms.
