  • Whats ground? Is it the point defined as 0 V of potential or voltage . . .
    Edit Sep 22 2021 The following image helps clarify the structure of my questions (I'm adding it in case someone reads these questions in the future ) I think that what The Photon defined as ground (the node with respect to which we measure the nodal voltages), should actually be the definition of reference node, and that we should define ground as the node point region in space defined as
  • What does 0 V exactly mean in an electric circuit mean?
    The discussion revolves around the meaning and implications of 0 V or ground (GND) in electric circuits, particularly in the context of mechatronics and electronics Participants explore various interpretations of ground, its role in circuit diagrams, and its significance in measurements and circuit design Some participants explain that 0 V or GND serves as a return path for the power supply
  • Why is the Digital 0 not 0V in computer systems? - Electrical . . .
    I'm taking a computer system design course and my professor told us that in digital systems, the conventional voltages used to denote a digital 0 and a digital 1 have changed over the years Appar
  • What does applying 0 Volt to a circuit means? - Physics Forums
    Another participant argues that 0V is not equivalent to a short circuit, emphasizing that a short circuit involves 0 resistance and that 0V can occur in various contexts, including open circuits There is a suggestion that the context of the question is important, with a mention of zero volt release switches
  • How is the voltmeter reading 0V in this circuit?
    However, when measuring the voltage with a voltmeter in the left circuit, it displays 0V I don't understand why the left circuit measures 0V instead of 1V What is the reason for this? (Comment: Thank you to everyone who responded to my question about the illogical circuit
  • Ground vs. Earth vs. common vs. negative terminal
    Ground Earth 0V Common Ground and earth mainly come from AC electricity They are used interchangably today In AC power distribution you literally connect one side of the circuit to the ground earth terra 0V came into use because its simple
  • Prove that 0v = 0 for an arbitaryvector v belong to V
    Homework Statement Suppose V is a vector space over F Prove that 0v (vector) = 0 (vector) for an arbitrary vector v belong to V Homework Equations
  • If live neutral alternates, why is neutral always $0V$?
    Voltage is a type of potential - electric potential This means voltage is meaningless unless it is expressed with respect to a reference point This reference point is the neutral line, defined to be at $0V$ The hot line then alternates between $\text {neutral voltage}\pm 240$ (technically more since the maximum voltage for $240V_ {rms}$ is greater than $240V$) Technically speaking, if the
  • electrostatics - Why do I measure 0 V between the negative pole of a . . .
    Thank you for the good answer! The other question might remain; Why do I measure 0V to the ground with a normal 1 5 V Battery, when I do not close the circuit
  • Why is there a voltage difference between these two grounds?
    The measured voltage on combinations like A A, A B, D C was expected But what I did not expect was the measured voltage on combinations like A C, A D and B C I was expecting both the power sources to be +5V and both grounds to be 0V relative to each other Meaning there would not be a voltage difference between A and C for example But this is clearly not the case From searching the web it
