A: A DELTA transformer is a 1:1 voltage transfer delta to Y IS 1:2 voltage transfer. That is for 3 phase system, If the phases are not exactly matched or the voltage is not exactly right then on a Y setup there will be circulating current at the common node.

What is the relationship between time charge and current?
Yes current = charge / time = I = Q/t
What is the difference between Load Current Line Current and Phase Current?
A load current is a current drawn by an electrical load. In other words, it is the current flowing from the source to the load.For a single-phase system, a line current is a current flowing through the line, or 'hot', conductor, while the current through the neutral conductor is called the neutral current.For a three-phase system, the three 'hot' conductors between the load and the source are called 'lines' and, so, the currents passing through them are called 'line currents'. For a three-phase system, loads are either connected between line conductors (delta-connected system) or between each line and the neutral (star- or wye-connected system), and represent the phases -so the currents passing through the loads are called 'phase currents'.For a balanced three-phase system, the line current is 1.732 times the value of a phase current, where the phases (loads) are connected in delta. For phases (loads) connected in star (or 'wye') the line current is numerically-equal to the phase currents.
What is the relationship between current and voltage in a thermistor?
V=IRR changes as a result of the change in temperature.
What is the current relationship with Finland and the US?
Ireland and the U.S. are tight like spandex on a fat guy.
What is the relationship between the deflection of the wire and the current?
the relationship between the deflection of the wire and the ccurrent is when the voltage is 12volt the current become higher.Another AnswerPresumably you are referring to the force on a conductor placed in a magnetic field? In which case, it is equal to the Flux Density of the field (in teslas), the length of the conductor within the field (in metres), and the value of the current passing through the conductor (in amperes).
What is the relationship between resistance and current in a resistive circuit?
:) It's connected together
When you connect cells in series which two quantities are the same for all cells?
When battery cells are connected in series and a conducting circuit is connected between the terminals of the string, the current out of the positive terminal of each cell and the current into the negative terminal of each cell are all the same number.
Why there is a relationship between current and voltage?
because current is the ratio of voltage and resistance.
How is an multimeter connected to take a measure?
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,
The relationship between current assets and current liabilities is important in evaluating a company's?

How many volts is in ten watts?
Volts and watts are different quantities and their relationship also includes the electric current. Voltage times current in amps equals the power in watts use.
What is the relationship between ohms resistance and amps for current?
The relationship is expressed by Ohm's Law: V=IR (voltage = current times resistance).

i think it is good !
Who discovered the relationship between the electric current and resistance?
This relationship was discovered by Karl Georg Ohm.
The relationship between current account balance and GDP?
The relationship between the current account balance and the GDP is that they both reflect the production in the given economy. They both deal with the net production.
What is the relationship between time charge and current?
