Phase Difference Between Voltage And Current In Inductor
For a capacitive load the current leads the voltage by 90 voltage lags current.
Phase difference between voltage and current in inductor. If we represent these phase angles of voltage and current mathematically in the form of complex numbers we find that an inductor s opposition to current has a phase angle too. For a resistive load there is no phase difference between current and voltage. Mathematically we say that the phase angle of an inductor s opposition to current is 90 meaning that an inductor s opposition to current is a positive imaginary quantity. If it s in the wires between the source and the inductor then the answer given by dale applies.
For an inductive load the voltage leads the current by 90 current lags voltage. It is customary to use the angle by which the voltage leads the current. The phase difference is 90 degrees. Current lags voltage by 90 in an inductor.
Understanding the preceding concept is quite important in ac circuits. Hence these two voltages get deducted and the resulting difference is the net voltage across these two differing from resistance voltage by 90 degrees in phase. The phase is negative for a capacitive circuit since the current leads the voltage. So measurement of phase angles is rather tricky.
The voltage of the supply leads the voltage across the resistor by ϕ tan 1 0 26 106 5 0 14 and the voltage across the non deal inductor leads the voltage across the resistor by θ tan 1 0 26 6 5 2 3. Capacitor and inductor have opposite reactions to current and their voltages are in phase opposition to each other. This means they differ in phase by 180 degrees. If it s the resistance within the coil then the answer given by vilvanesh applies.
If it is distributed between the wires and the coil you would need to specify the amounts to determine the voltage across the coil and its phase. This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit.
