## What happens if a circuit has C and/or L?

In a series configuration, XC and XL cancel each other out. In real, rather than idealised, components, the current is opposed, mostly by the resistance of the coil windings. Thus, the current supplied to a series resonant circuit is maximal at resonance.

## What is XL and XC?

Reactance is measured in ohms ( ). There are two types of reactance: capacitive reactance (Xc) and inductive reactance (XL). The total reactance (X) is the difference between the two: Total Reactance, X = XL – Xc.

**What is the C circuit?**

The circuit that is excited using alternating source is called an AC Circuit. The alternating current (AC) is used for domestic and industrial purposes. In an AC circuit, the value of the magnitude and the direction of current and voltages is not constant, it changes at a regular interval of time.

### What is J in Z R jX?

This is actually a general way to express impedance, but it requires an understanding of complex numbers. This is the only way to calculate the total impedance of a circuit in parallel that includes both resistance and reactance. Z = R + jX, where j is the imaginary component: √(-1).

### What is L circuit?

Inductor is an electrical component that stores energy in magnetic field. The inductor is made of a coil of conducting wire. In an electrical circuit schematics, the inductor marked with the letter L. The inductance is measured in units of Henry [L].

**When L is removed from the circuit?**

When L is removed from the circuit, the phase difference between the voltage and the current in the circuit is 3π. If instead C is removed from the circuit, the phase difference is again 3π.

#### How do you find C from XC?

Similarly for XC = 1 / (2 x pi x f x C) first take the reciprocal of both sides: 1 / XC = (2 x pi x f x C). Now divide both sides of the equation by (2 x pi x f) to leave C = (2 x pi x f) / XC.

#### How do you calculate C from XC?

Capacitive reactance is defined as:(10-1)Xc=1/ωC=1/2πfCwhere XC is the capacitive reactance, ω is the angular frequency, f is the frequency in Hertz, and C is the capacitance.

**How do you calculate XC?**

## What is JX in impedance?

A complex impedance is build up with a real part (R=resistor) in series with a imaginary part (+JX = coil or -JX = capacitor). A complex impedance is indicated with the the letter Z, and the unit is Ω. The notation of a complex impedance can be Z=R+JX. In this case a resistor and coil are series connected.
