The voltage across a resistance is in phase with the current through the resistance because the resitance in non-reactive, i.e. non-inductive and non-capacitative.

In the inductive case, the load resists a change in current. In the capacitative case, the load resists a change in voltage. In the resistive case, the load current follows the voltage with no delay, hence there is no phase differential.

What is the Phase resistance of 500 voltage?

Phase resistance refers to the resistance encountered by current in a single phase of a multi-phase system, such as a three-phase electrical system. It is not directly determined by the voltage level, like 500 volts, but rather depends on the characteristics of the load and the conductors in the circuit. To determine the phase resistance, one would typically need to know the current flowing through the phase and the power factor of the load. If you have specific details about the load or system, I can help calculate or explain it further.


In 3 phase voltage increases and current decreases why?

If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.


What is the phase shift between voltage and current when an capacitance is connected to the circuit?

The amount of phase shift depends on the resistance that is also present in the system. In an ideal situation, the phase shift would be +90 degrees, but that would require a voltage source with zero resistance, conductors with zero resistance, and an ideal capacitor that exhibited only capacitance.


Why do you have voltage to ground but not voltage phase to phase?

There is phase to phase voltage in 3 phase system.AnswerYou don't get voltage 'phase-to-phase'; it's 'line-to-line'!


How does coil resistance affect angle between the current in a resistor and the current in an inductor?

Coil resistance affects the phase angle between the current in a resistor and the current in an inductor by influencing the total impedance of the circuit. In an inductive circuit, the presence of resistance causes the current to lag behind the voltage, reducing the phase difference. Higher resistance results in a smaller angle, as the resistive component (which is in phase with the voltage) becomes more significant compared to the inductive reactance, which causes the current to lag. Consequently, the angle approaches zero as resistance increases, indicating that the current becomes more aligned with the voltage.

If you have a phase to phase voltage how do calculate the overall voltage?

First of all, there is no such thing as a 'phase-to-phase' voltage. The correct term is 'line-to-line' voltage. Secondly, without knowing what you mean by 'overall voltage', there is no way of answering your question.

What is current and voltage waveforms are in phase?

If current and voltage of an AC are in phase, then the "power factor" is 100%, and the load is a pure resistance, with no inductive or capacitive reactance (at least at the operating frequency of the AC).


In 3 phase voltage increases and current decreases why?

If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.

What does voltage current mean?

V=IR, voltage is directly propostional to current and resistance (by ohm's law).CommentVoltage is not 'proportional to resistance'. Resistance is a constant, and is not affected by voltage at all.


When phase and neutral will short means what will be the voltage in neutral?

If the phase and neutral wires are shorted together, the voltage in the neutral wire will be the same as the phase voltage. This is because the short circuit effectively bypasses any impedance or resistance in the circuit, causing the potential difference between the phase and neutral wires to be equal.
