Does voltage vs current graph passes through origin?
Yes. While it isn't clear what device you are talking about, and different devices have different characteristic curves (for example, a straight line for a resistor), a voltage is required for a current to flow, so if there is no voltage, there won't be any current, either.
Why Base Transceiver Station equipments require negative 48 volt DC to function properly why not positive?
it has two reasons.one is to prevent corosion due to the elecrtolitic effect and the other is to protect operator from the line voltage.. it has two reasons.one is to prevent corosion due to the elecrtolitic effect and the other is to protect operator from the line voltage..
Another term for potential difference is?
voltage
How would you use typical in a sentence?
That is so typical of you!I'm so testy because that 'typical typing test' tripped me up!Three eyes are not typical to the fish from this pond...
What is needed to calculate the voltage across a device?
you calculate a voltage circuit by taking it apart and findng the circuit and calculate the voltage and then resible it.
How the voltage regulation in 33kv line?
It does not depend on the line. The regulation is the percentage change in voltage caused by applying the full load current, and that depends on the transformer supplying the line. A value of 5% would be typical.
Is transmission voltage a phase to phase voltage or a phase to ground voltage?
Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.
What is the typical line voltage for gas furnaces?
For the internal fan operation, 110v AC is the standard. For thermostat control, usually low voltage, like 12 or 14 v DC.
What is edge speed in electronics?
A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line. A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line.
How do you convert 3 phase RMS line-line voltage to RMS line-neutral voltage on an unbalance system Basically how do you calculate using trig for all 3 phase?
The term, 'unbalanced system' refers to an unbalanced load. Under normal circumstances, an unbalanced load leads to unbalanced line currents. The line voltages are determined by the supply and remain symmetrical, even when the load is unbalanced. As your question refers to a 'line to neutral' voltage (i.e. a phase voltage), you must be referring to a star (wye) connected load, in which case the phase voltage (line to neutral voltage) is 0.577 (the reciprocal of the square-root of 3) times the line voltage (line to line voltage).
Is 220V line voltage or phase voltage?
Phase, if you are referring to line, as power line from pole.
What is the line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
What is a line to line voltage?
In a 3 phase system, the voltage measured between any two phase is called line to line voltage.And the voltage measured between line to neutral is called phase to neutral (line to neutral) voltage.AnswerThere is no such thing as a 'phase-to-phase' or a 'phase-to-neutral' voltage. The correct terms are 'line-to-line' and 'line-to-neutral'.The voltage between any two line conductors is called a line voltage.In a three-phase, three-wire, system, the line voltage is numerically equal to the phase voltage.In a three-phase, four-wire, system, the voltage between any line conductor and the neutral conductor is called a phase voltage. The line voltage is 1.732 times larger than the phase voltage.
How match 2 phase line voltage between them?
To match 2 phase line voltage it has to be the same voltage.
What is line regulation?
Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.
What voltage should 208 3 phase leads read?
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
Is line voltage or phase voltage mentioned on transformer nameplate?
It depends how they are connected. If they are connected between line conductors then they are measuring line voltages. If they are connected across phases then they are measuring phase voltages.
