Why there is no phase difference between voltage and current?

There is no phase difference between voltage and current and the current and voltage is said to be in-phase. Complete step by step answer: It is given that the circuit is pure resistive which means that there is a resistor in the circuit along with an AC source.

What is the phase difference between voltage and current for a purely resistive load driven by a sinusoidal voltage source?

When a sinusoidal voltage instantaneous value, ν is applied to a pure inductor L, the sinusoidal current i lags the voltage by 90°.

What is the phase voltage relationship of voltage and current in a resistive load?

The relationship between voltage, current, and resistance is described by Ohm’s law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.

What is the phase difference between current and voltage in a circuit having only resistor?

The phase difference between current and voltage in an AC circuit is 4π​ radian.

What does phase and phase difference mean?

Phase: The position of the moving particle of a waveform is called “Phase” and is measured in “Radians or degrees”. Phase difference: The time interval by which a wave leads by or lags by another wave is called “Phase difference” or “Phase angle”.

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

The voltage and the current are said to be “in-phase” since their zero, peak, and valley points occur at the same time. One cycle is often referred to as 360o, so it can be said that the current lags the voltage by 90o. This phase shift occurs because the inductive reactance changes with changing current.

What is the phase difference between voltage and current of purely inductive circuit?

The applied voltage must be equal and opposite to the self-induced EMF at all times; therefore, the current lags the applied voltage by 90° in a purely inductive circuit.

What is the phase difference?

The phase difference between two sound waves of the same frequency moving past a fixed location is given by the time difference between the same positions within the wave cycles of the two sounds (the peaks or positive-going zero crossings, for example), expressed as a fraction of one wave cycle.

In which case the current is in phase with the voltage and why?

Current is in phase with voltage when there is no phase shift between the sinusoids describing their time varying behavior. This generally occurs when the load drawing the current is resistive.

What is the phase difference between voltage and current for purely inductive circuit?

When current is in phase with voltage?

“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.
