Phase Difference Formula:
From: | To: |
Phase difference represents the relative timing offset between two sinusoidal signals. It indicates the delay or lead of one signal compared to another and is typically measured in radians or degrees.
The calculator uses the phase difference formula:
Where:
Explanation: The formula calculates the actual phase difference by multiplying the measured division difference by the angular measurement per division.
Details: Phase difference measurement is crucial in signal processing, communications, power systems, and electronic circuit analysis to understand signal relationships and timing characteristics.
Tips: Enter phase difference in divisions and degree per division. Both values must be positive numbers. The calculator automatically converts degrees to radians for accurate results.
Q1: What is phase difference measured in?
A: Phase difference is typically measured in radians or degrees, with radians being the standard unit in mathematical calculations.
Q2: How is phase difference measured on an oscilloscope?
A: On an oscilloscope, phase difference is measured by comparing the horizontal displacement between two waveforms and multiplying by the degrees per division setting.
Q3: What does a phase difference of 0 mean?
A: A phase difference of 0 means the two signals are perfectly in phase - their peaks and zero crossings occur at exactly the same time.
Q4: What does a phase difference of π radians (180°) mean?
A: A phase difference of π radians means the signals are completely out of phase - when one signal is at its peak, the other is at its trough.
Q5: Why is phase difference important in AC circuits?
A: In AC circuits, phase difference between voltage and current determines the power factor, which affects the efficiency of power transmission and consumption.
