What is the current in the series LCR circuit?

When a constant voltage source or battery is connected across a resistor, current is developed in it. This current has a unique direction and flows from the negative terminal of the battery to its positive terminal. The magnitude of current remains constant as well.

Why does the current in an RLC series circuit oscillates?

Once the capacitor is discharged, the inductor resists any change in the current flow, causing the capacitor to be charged again with the opposite polarity. The voltage in the capacitor eventually causes the current flow to stop and then flow in the opposite direction. The result is an oscillation, or resonance.

What is LCR Power Factor?

The power factor of an LCR circuit is the ratio of the resistance to the total impedance of the circuit. The total impedance consists of the magnitude of the phasor sum of the resistance, the capacitive reactance and the inductive reactance. Therefore, the power factor of an LCR circuit at resonance is 1.

What is LRC series circuit?

An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.

How do you find the peak current in a LCR circuit?

Since the circuit is at resonance, the impedance is equal to the resistor. Then, the peak current is calculated by the voltage divided by the resistance. The resonant frequency is found from Equation 15.6. 5: f0=12π√1LC=12π√1(3.00×10−3H)(8.00×10−4F)=1.03×102Hz.

What is the phase relation between current and voltage in LCR circuit?

In an electrical circuit R, L, C and an a.c.voltage source are all connected in series. When L is removed from the circuit, the phase difference between the voltage and the currentin the circuit is π/3.

What is the formula of power factor in LCR circuit?

Power factor of series R−L circuit is given by cosθ=R2+ω2L2 ​2R​
