Reactance is the property of an electrical component to oppose the change in current while impedance is the combination of resistance and reactance. There are two types of reactance: Capacitive & Inductive
electrical resonance in a circuit when the inductive reactance and the capacitive reactance are equal in magnitude electrical resonance occurs. the resonant frequency in an lc circuit is given by the formula \(\begin{array}{l}\omega =\frac{1}{\sqrt{lc}}\end{array} \) \(\begin{array}{l...
For a simple RC low pass filter, cut-off (3dB point) is defined as when the resistance is the same magnitude as the capacitive reactance Decibel Unit Gain is often measured in decibels, reflecting the logarithmic way our ears perceive sound. This unit measures the power or voltage ratio ...

The working of this capacitor mainly depends on the capacitive reactance principle. It is nothing but how the impedance of a capacitor alters with a signal frequency that is flowing through it. A nonreactive component likea resistoroffers similar resistance to a signal apart from the frequency of...
series circuit? Write the formula for resonant frequency. Solution Verified by Toppr The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase. The sharp minimum ...
Admittance For Parallel Circuit Branch ‘A’ consists of an inductor with inductive reactance XLconnected in series with a resistor with resistance ‘R1‘. Branch ‘A’ is connected in parallel with branch ‘B’. Branch ‘B’ consists of a Capacitor with capacitive reactance XCin series with a...
In AC circuits, impedance is playing the same role, as resistance is playing in DC circuits. The complex quantity impedance is the combination of reactance and resistance and reactance is a combination of inductive and capacitive reactance. Fortunately, the above transformation is true for AC circui...
We know that the formula for area of trapezoid, A = (½) [(a+b)h] square units Substituting the values in the formula, we get 75 = (½)[25h] 75/25 = (½)h 3 = h/2 h = 6. Therefore, the height of the trapezoid is 6 m. ...
capacitive reactance of the power factor correction capacitors. There are various types of power factor correction capacitors such as ABB power factor correction capacitors, fixed power factor correction capacitors, and automatic power factor correction capacitors, which are typically used for power factor...
