What is the phase of the current at resonance?

At resonance, the voltage across the inductor and the voltage across the capacitor are the same at any instant but they are 180 0 out of phase with each other. They cancel each other out so that the voltage drop across RLC circuit is due to just the voltage drop across the resistor alone.

Why is current and voltage in phase at resonance?

At resonance the voltage across the inductance and the capacitance will be 90 degrees out of phase with the current but in opposite directions. So the current will be in phase with the applied voltage and the voltages across the reactive components could be quite large. There are two basic circuits.

What is the phase difference at resonance?

At resonance the phase angle between the displacement and applied force is either +90-degrees or -90-degrees. The imaginary number, either +I or -I, of course represents a plus or minus 90-degree phase shift.

What does it mean when current and voltage are in phase?

“In phase” means that the AC voltage and current vary together in time; when the voltage reaches its peak so does the current, and when the voltage is zero, so is the current. The instantaneous current is always proportional to the instantaneous voltage.

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

In a series LCR circuit, the phase difference between the voltage and the current is 45^∘ .

What is the phase difference between voltage and current?

The phase difference between current and voltage in an AC circuit is π4 radian.

Why is resonance called voltage resonance?

Why is a series resonance circuit also known as voltage resonance? – Quora. In series circuit, current is common to both capacitor and inductor, while voltages across these two are equal and opposite, and cancel each other. This is voltage resonance.
